Thanks David. I'll have a search about in the archives. I've been 
reading plenty of stuff on the web and I know a fair bit more about DVB 
today than I did yesterday! I had a look at the megalithia site and I 
have good line of site to Billsdale (no obstructions) and I'm 21 miles 
away. Since I already have a good loft space aerial I'm going to borrow 
a friends set top box over the weekend and see what kind of reception I 
get from it. If it's not great I'll have to have an outdoor aerial fitted.

With regard to Myth choosing the second tuner, I had assumed that it 
would use the first input (my 250) unless there was a conflict and then 
try to resolve it using the new input (Nova-T) is this the case ?

Excellent, thanks for the advice. I've been looking at the Nova-T cards 
today. With the above in mind I think I'll schedule an FC4 upgrade in 
the next couple of weeks. I already upgraded from FC2 to 3 in the middle 
of last year when FC2 went legacy so it shouldn't be a big hardship.

Is there any additional information I need to know to get the Nova-T 
going or is it just a case of the right modules ?

[mythtv-users] Advice on adding second capture card

[Paul Barker]

Hi All

Well my myth setup has been working great for over a year now so I thought
it's about time I broke it! I'd like to add a second capture card to the
system. Currently here's what I have:

Athlon XP 2000
512Mb Ram
1 X 160Gb Seagate Baracuda 7200RPM 2Mb cache dedicated capture / buffer
device.
Fedora 3 (going to 4 when 5 releases)
PVR-250 capturing over SVID from SKY reciever

I'd like to add a DVB-T card to the above, so I need advice on a few items:

1) Card recommendations. Something that will work well with the 250 and is
reliable.
2) Disk bandwith. Can I get away with one drive if I wanted to record 2
programs and watch a recorded show at the same time ? (This would be
pretty unusual but ...)
3) Good general resources for DVB under Linux since I know pretty much
nothing about DVB.

I have another spare Baracuda so I could stripe the capture device but I'm
trying to have the minimum number of drives in the server to keep heat /
power consumption down.

Cheers
Paul

I played with this at FC2 and FC3 and I needed to recompile the kernel 
to enable NFS root support (NFS had to be builtin not modular) and 
Kernel level IP config.

 From my notes it looks like these are mainly what I played with:

Kernel level IP configuration (CONFIG_IP_PNP_ENABLE plus CONFIG_IP_PNP_DHCP)
NFS Support (CONFIG_NFS_FS, CONFIG_NFS_V3 and CONFIG_ROOT_NFS)

But check - my notes are OLD - have a look in the current config screens 
/ file and check the kernel docs where appropriate.

Hope it helps.

Hi Neil

Try modinfo on the module. I guess that you didn't get any errors during 
the build ? Also look in dmesg after the insmod. If you could post the 
full error that may help. It's possible it's not an error from insmod 
but from the module itself.


I have a development FC3 box here so I could try building a binary for 
you if all else fails.

[mythtv-users] Watching recordings. Pause then drop back to selection screen

[Paul Barker]

Hi

I have a strange issue which is apparent on both of my frontends. Whilst 
watching a recorded program the image will freeze and eventually drop 
back to the selection screen.


Here is a log snippet from one frontend :

2005-09-27 11:55:11.948 waiting for prebuffer...


One of my frontends is in another room and I had been wondering if I had a 
cabling issue, but the above comes from a frontend plugged into the same switch 
as the backend.

At the point of failure the backend log doesn't show any errors (logging 
verbose for playback,file,network) and if I restart the playback it will 
happily run past the point of failure but then may ( or may not) fail again 
later.

I've tested all my patch leads with a cable tester and 'sar -n ALL' on the 
backend shows no collisions or tx or rx errors.

The b/e is FC3 kernel 2.6.12-1.1372_FC3, one f/e is the same and the other is 
minimyth.

Any ideas where to start ? Or do I just need to start with ethereal and capture 
a session ?

the n00b question, but I have not had to deal with this before :)

I am running an FC4 box using Axel's RPMs with an NVidia 5500 card
... if that helps any

Thanks again... WAF is extremely HIGH and this would put it over
the edge (meaning I would be allowed to buy more "toys" w/out
questions...)

I seem to remeber that it may be a permissions problem on the virtual x 
display created by Xvfb. I had a similar problem.


Check mythburn/scripts/remplex.sh for a line similar to the following:

  ${XVFB} :33 -screen 0 640x480x8 2> /dev/null > /dev/null &

I changed the line by adding the -ac flag:

  ${XVFB} :33 -ac -screen 0 640x480x8 2> /dev/null > 
/dev/null &


which tells Xvfb to allow all clients to connect. I think you may be 
able to create a X29.hosts file and point Xvfb at it (with the -auth 
parameter?) which contains a list of hosts allowed to connect, but using 
the -ac and allowing anyone worked for me.


Hope it helps

Hi Jeremy

Sorry for not replying sooner - I've been offline for few days. Is this 
still a problem ?


I'm guessing that the --key_buffer=16M option is what is preventing 
mysql starting. I'm using the same version of mysql as you (guess you 
may be on Fedora ?)


My /etc/my.cnf looks like this :


[mysqld]
#datadir=/var/lib/mysql
datadir=/share/db
socket=/var/lib/mysql/mysql.sock

[mysql.server]
user=mysql
basedir=/var/lib
set-variable = key_buffer = 16M
set-variable = table_cache = 128
set-variable = sort_buffer = 2M
set-variable = myisam_sort_buffer_size = 8M

[safe_mysqld]
err-log=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid


As you can see it's using the set-variable syntax to set key_buffer. 
Check in your's - it may be you have an my.cnf hanging around from an 
older install of mysql. I vaguely remember the syntax changing at some 
point. In case you're not aware (and forgive me if this is sucking eggs 
time ;-) don't just cut and past my example above. I keep my databases 
in a different filesystem from default so it probably won't work for you 
(see the datadir= line).


Let me know how you get on.

I'm looking at putting together a MythTV box, and I came across this

It's a reasonable price, but it's based on a Via chipset, and I read

Has anyone played with this hardware, or have recommendations that I 
should go with this or pieces-parts from newegg?


Thanks!

 

I have the same board sitting in the family room running as a diskless 
front end via mini-myth (http://www.linpvr.org). I really like the EPIA, 
especialy when using the hardware mpeg decoder. The TV ouput quality is 
really good IMHO (for SDTV - no HD here in the UK yet). If you're buying 
it for a combined fe/be be advised that transcoding and commercial 
flagging may be slow due to the processor speed. Also the 'goom' 
visualisation in MythMusic does not run well on this box even when using 
the correct dri and Unichrome drivers. Not exactly a show stopper but 
it's my favourite visualisation ;-)


Personally I'd want 512Mb of RAM but I bet there are plenty of folks on 
the list will argue that 256 is enough.


Overall I'd recommend this board whole heartedly as a front end solution 
- for a backend ... with a PVR 250 / 150 etc (ie hardware encoder) it 
should go well enough I guess.

I've been using this machine (ASRock SiS motherboard, Athlon 2400XP,
Geforce FX 5200, 2xPVR250) for a year now and have had no screen
corruption or lockups. So I'm not sure exactly what your problem
is/was, but it seems to be an isloated incident.
 

No big rivet probs on my LC11M but getting a VGA connector into an AGP 
card (or a motherboard with integrated VGA) is tight simply due to the 
low height of the case. The VGA cable buts up against the edge of the 
case bottom and it is a fiddle to get a good connection. I figure no 
worries since I'll be using the svideo once I get this box into production.


I'm currently using the AGP / PCI riser to run a Geforce 4 MX in an AGP 
slot without issues. The system has only been up for a day though so 
fingers crossed.


I don't have SATA drives so I can't comment on the drive cage issue. 
Also I did have to cut the internal frame slightly and move a fan to get 
my big Zalman flower heatsink in ;-)


The one major problem with mine was the VFD was dead on arrival and I 
ended up having to RMA it to Germany (I'm in the UK). I have to say that 
the Tech Support guy (Stefan) was great and I'm expecting a brand new 
VFD in the next couple of days. Still a bit of a bummer though since one 
of the big deciders for me was the inbuilt VFD / IR Reciever and I 
*still* haven't got to play with it :(

Look closely at the shebang line and you'll see a ^M - that's DOS /

I had the exact same error using the SUN JSDK. I think what fixed it for
me was setting the JAVA_HOME and CLASSPATH environment variables
correctly. Look in either install.sh or install.bat (yes I know thats for
DOS) files for clues as how to set it as I'm not sure where the version of
Java you're using keeps things.

I'd second the recommendation of both the EPIA and MiniMyth. Booting from
the network means no need for a hard drive in the frontend. It really is
pretty easy to set up too. I run an Epia M1 motherboard in a VIA
Serenti case. It's not too bad but the fan in the power supply needs to be
quieter. The plus side is that it'll take a normal factor CD / DVD ROM and
has an IR window to allow you to add an IR reciever. They're not that easy
to find but are relatively cheap and make a great starter case. There is a
picture of one right on the front page of this site:
http://www.icp-uk.com/ . Check out  the online store here:
http://www.mini-itx.com/ and KustomPCs: http://www.kustompcs.co.uk/ for
other cases. I'd recommend shopping around though. I found my new case
(see below) £50 cheaper at http://www.scan.co.uk than pretty much anywhere
else even though they're not big on HTPC cases.

For my main box I've just bought a Silverstone LC11M and I have to say its
the cat's whiskers. It just looks superb and the iMon remote looks great.
I can't wait to start building it this weekend. (Cue battling with lirc /
lcdproc to get the iMon remote and VFD working)

wouldn't using the minimyth distribution solve the problem of properly
mounting a flash device?  I haven't tried it.

 

I just built a MiniMyth frontend on an EPIA M10K. It was up and running 
in about 20 mins plus about half an hour for tweaking settings etc.


I really can't recommend this enough. It has full Unichrome support so 
you get H/W acceleration of MPEG. Since my b/e has a PVR250 that means 
that live and recorded shows hardly scratch the CPU. It's so easy to set 
up and has everything you need including a basic telnet server and X VNC 
so you can play with the node remotely if need be.


Basically (for those who don't know) you get a kernel, a root file 
system image compressed with cramfs and a config file. All you need is a 
dhcp server and a tftp server. The client grabs the kernel and rootfs 
image and boots the kernel and mouts the filesystem as a RAM disk. The 
config file controls the setup of each client setting things like lirc 
driver, locations for video / music etc.


If you're thinking of netbooting frontends head on over to linpvr.org 
and check it out.

The chown errors suggest that you don't have the mysql user and group on

Hi

Erm, yes that would have been a good idea wouldn't it :(

I'm running a build with the output tee'd to a logfile now. It's going
to be large so I guess I'll post the failing section first.

This looks more an more like a library path issue BTW. I did a bit of
experimentation and made a symlink from /usr/X11R6/lib/libviaXvMC.so.1.0
to /usr/lib/libviaXvMC.so and tried a ld -lviaXvMC and it found the
library. I can't understand why this is though since the ldconfig -p
lists the library. (ld -lXvMC fails also BTW)

I've removed that link for this build to get a true failure.

Yep I checked 
that:
 
[EMAIL PROTECTED] etc]# 
ldconfig -p | grep via    
libviaXvMC.so.1 (libc6) => 
/usr/X11R6/lib/libviaXvMC.so.1    
libviaXvMC.so (libc6) => /usr/X11R6/lib/libviaXvMC.so
So it's in the 
ld.so.cache but if I do ld -lviaXvMC I get
 
[EMAIL PROTECTED] etc]# 
ld -lviaXvMCld: cannot find -lviaXvMC
(I've also tried 
moving ld.so.cache and re-running ldconfig - same result 
after)
 
Hmm, any ideas 
?

Cool, let me know how you get on. I'd be interested if it works 
!
 
Cheers

Re: [mythtv-users] RAID on Fedora Core 3?

Hi
 
AFAIK its a bad idea 
to put slave IDE devices into a software RAID set. Firstly it will upset 
performance and secondly there's a good chance that if you lost one of the disks 
on that channel then it would take out the other also. (ie loose the Primary 
master and the Primary slave goes too. So even if the Primary slave wasn't 
physically bad you'd still end up doing recovery on both 
arrays)
 
I have 2 X 2 channel 
PATA cards and tried putting slave devices on and I had problems even getting 
the OS to see the drives properly to create the RAID set. Got timeouts etc 
trying to bring a RAID5 set online. I now have 4 disks on these 2 controllers in 
RAID5 all on the masters and a RAID1 set for my OS on the motherboard IDE 
masters.
 
I guess there's no 
harm in trying, YMMV but I think even the RAID howto it advises against 
it.
 
Cheers
 
Paul

[mythtv-users] Sound Issues with VIA 82xx

[Paul Barker]

Title: Message



A while back I 
posted saying that I was having issues with sound using a front end with 
embedded VIA 82xx audio and an optical digi out. Basically whenever I went into 
TV / Music etc I got no sound until I muted the IEC switch in the mixer. Each 
time I exited and went back into to TV or anything else the switch was turned 
back on and the problem returned. (This is an FC1 box by the 
way).
 
I'd tried all sorts 
of things to get it going but eventually lived with a work around script which 
checked the switch every 5 secs and turned it off if it was 
on.
 
Well I finally sat 
down and dedicated some time to find out exactly what the problem 
was.
 
It turns out that 
the IEC958 switch basically turns the optical digi out on and off. Something 
turns this on (possibly at boot but certainly each time I go into TV or Music or 
whatever) and my AV amp is set to auto source select. Iit sees light on the 
optical in then it tries to use the digital input. I'm assuming that the 
signal on the optical line is not the correct format and hence no sound. If I 
manually switch over to the analog on the amp then, hey presto, sound 
!
 
So ... either the 
optical out shouldn't be on all the time (ASLA driver ? / OSS ? / Myth ?) or I 
need to direct all my output to the optical out but get ALSA to convert the rate 
etc into the correct mode.
 
A couple of 
questions: 
 
1) Is Myth turning 
on the optical ? (I'm not set to use it by default but if I set it to use 
ALSA:plug:spdif I get sound in TV but Music won't use it - error could not open 
sound device).
 
2) Can ALSA do the 
rate convert so I could ship all my output to the optical and would this be a 
good solution ?
 
If 2 is possible 
some pointers to some good resources on asoundrc from the point of view of an 
ALSA newbie would be good :) I'm not looking for the answer on a plate (but if 
you have one plated up ... ;) ) and I'm a Systems Engineer so can probably work 
it out with some decent reference material.
 
Thanks, as always 
for any and all help. If anyone's interested I'll post a 
conclusion.
 
Paul
