Hi Everybody,
I can't seem to get my PVR-150 to work. All I get is static for audio and no
video. As far as I can tell it's a tuner problem since I can modprobe ivtv
with tuner=50 or tuner=55 or any other random tuner type and I don't see a
single difference in behavior.
When I try to tune to a channel, I do not get any signal:
smokin-joe firmware # ivtv-tune -c2
/dev/video0: 55.250 MHz
smokin-joe firmware # ivtv-tune -c4
/dev/video0: 67.250 MHz
And some more indications of problems with the tuner.
smokin-joe firmware # v4l2-ctl -I
Video input : 0 (Tuner 1)
smokin-joe firmware # v4l2-ctl -F
Frequency: 0 (0.000000 MHz)
smokin-joe firmware # ivtv-tune -c13
/dev/video0: 211.250 MHz
smokin-joe firmware # v4l2-ctl -F
Frequency: 0 (0.000000 MHz)
smokin-joe firmware #
The only indication I ever get of the tuner doing something useful, is that
if I play the /dev/video0 device in mplayer, the audio static cuts out for
1/2 second shortly after using ivtv-tune to try to change a channel.
smokin-joe firmware # v4l2-ctl --all

Note that the tuner shows a signal strength of 0% and the frequency range of
0 to 0..............
Assuming it was something obvious, I tested the cable into the tuner and it
works fine with other devices. I also tried a different cable that was
hooked up to a working device and again no change in behavior. I'm
99.9%positive that I have good signal into the tuner. I'm on Comcast
analog cable
if it matters (NTSC)

That's the only irregularity I see.
In regards to the tuner, I see it detect it in eeprom and identify it as a
type 50 and then load the tuner module down the line but I never get any
feedback from the tuner module. If I unload the tuner module and reload it
with debug=3, still no dmesg output. Same if I load the tuner module with
debug=3 prior to loading ivtv. As I mentioned above, I've tried unloading
the ivtv and tuner modules and loading ivtv with tuner=50 (or various other
values) and I never see any difference in the output from dmesg. It's
identified in eeprom as a type 50 and the ivtv driver loads the tuner module
but I never see any indication that it's actually passing values to it or
doing anything useful - I just can't get any meaningful output from the
tuner module.
I'm on gentoo and I've tried installing both the firmware & driver from
portage and also uninstalling them and using the files from the
ivtvdriver.org site - same behavior in both.
Here are some pertinent detials on my system:

Something that jumped out at me in the ivtv how-to was this:
"For kernels <= 2.6.15 When you run a 'make install', you may have noticed
that there are warning messages about moving some modules.There are
duplicate modules for tveeprom, tda9887, tuner and msp3400. One set is
provided with the kernel (originating from from the v4l project, and merged
with the dvb project), and the other is from ivtv itself. Please see below
how to install the modules and which one will have to be used."
I can confirm that both the gentoo portage version and ivtv driver from the
site did NOT over-write my tuner module. Is this only applicable to earlier
versions of ivtv?
Any help appreciated. I'm pretty stumped on this one. If I can provide any
more information please let me know.
Thanks in advance!
Rob
