Hi Andy and Brandon, I too tried various different bufsizes as suggested and I still see very noticeable pixelation/tearing regardless of the setting.
I even upgraded my motherboard this past weekend to an Asus AM2+ board with
Phenon II X3 CPU. Still the same problems with the card in a brand new
setup.
I also tried modifying the cx18 source code as Andy suggested and that made more debug warning show up in my syslog, but still did not resolve the issue. Haven't tried this yet with the new motherboard though.
Is it possible that this card is more sensitive to hiccups in the signal coming from the cable line? Or interference from other close-by cables and electronic equipment?
When recording/watching Live TV through MythTV, I see that ffmpeg is constantly outputting various errors related to the video stream. I can post those here if you think it's relevant.
Shoud I just return this card and get one with a different chipset? Or do you think driver updates can solve the issue?
I'm happy to hold on to this card if it means I can contribute in some way to fixing the problem, if it's fixable : )
