Apparently there is a bug in the HX version of the PL2303 USB to serial hardware so I had to update my kernel to incorporate a work-around patch that went in 2.6.13. Details here: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg371 49.html It works fine now! Kieron Pareto Investment Management Limited is a Mellon Financial Company.

Nathan Hesson wrote: http://forums.fedoraforum.org/showthread.php?t=25219 I do Crestron programming and use serial ports everyday. I found that in windows M$ doesn't handle the voltage on the port right and it screws alot of stuff up. I suspect linux doesn't have this problem though. Thanks for that. But of course I left out what kernel I was running, sorry! It is SUSE 9.3 latest 2.6.11.4-20a kernel, which I guess already has the above fixes in. I'll try with the very latest kernel anyway, just in case something has been fixed... This evening I tried to rmmod the pl2303 and the usbserial kernel modules and re-add them, but it didn't make any difference. So, anyone know what's going on? Failing that, does anyone know how I can simulate a physical removal of the USB device and a re-insert programmatically? That will at least mean I can record some TV! ;) I searched around the Internet, couldn't find any commands that could do it... Thanks for any help!

Sorry, that should have been a "PL-2303" device.

However, I have just bought a new system without any serial ports and so bought a Manhattan USB to Serial converter (a PL2003 device that I am using with SuSE 9.3 - it did say something about "DEVPATH is not set" in the /var/log/messages file when I plugged it in).

Subsequent attempts to change channel still show the RedEye power being applied as normal (from the red power light) but the light does not pulse for the channels being sent like it normally does.

Re: [mythtv-users] XvMC jitters with 0.17
Bob Apodaca wrote: I had XvMC working great under 0.16 and I upgraded to 0.17 yesterday. The problem I am seeing now is that interlaced shows look awful because you can see the interlace lines as clear as day (previously they were unnoticable). I can clear this up if I turn on deinterlacing. AFAIK, turning on deinterlacing disables XvMC. If you have a nVidia card, and use the TV out, it is better to adjust the flicker fixer slider in the drivers. -- Kieron Wilkinson ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] scratchy sound troubleshooting
Kevin Brouelette wrote: I don't here the delayed tv sound but I do hear raw scratchy noise. So, the scratchy is coming from /dev/dsp [??] I've been changing settings in alsamixer but I haven't resolved the problem yet. I had a problem a bit like this. The way I resolved it was to do two things: 1) Turn down the volume to about half on the cable box 2) Unselect "Input Is Surround Sound" in AMix (I think, but I guess it shouldn't matter as long as the mixer you use shows the sound card switches) which is in the "switches" tab. This was the thing that made the most difference, before that the sound was terrible. Note that sound from XawTV etc., is direct from the line in, and so will be uneffected. I hope that helps! -- Kieron Wilkinson ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] Weird Freezing Problem - Hopefully My Last Problem

My system freezes and I don't even have to have mythfrontend open, just the backend. Intially I thought it was down to a faulty hard disk, but I had that replaced and it still happens. My data directory is two partitions striped together and ext3. I was thinking of changing both of those to see if it made any difference. The short time I used 0.15 I did not get crashes, so I have been thinking of going back to that to see if it makes any difference. I'll let you know if I have any success next week. -- Kieron Wilkinson ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
