I'm hoping I can get some help troubleshooting my problems with 2 PVR-500 cards that I have, as I don't really know what else I can do on my own.Problem: When using tuners, all channels are corrupted with a substantial (up to 50%) static.Things I've tried so far: If I plug the same cable into a tv, the channels come through clear. If I use composite inputs, everything is clear as well. I've tested in Myth and using ivtvctl/ivtv-tune--both methods yield the same snowy results. Initially, I tested both cards in the same box running mythdora 2.32 (FC4, ivtv-0.7-113). The mythdora system was a dual Opteron system running the Nforce Pro chipset--both cards exibited the same distortion.Since I already had a backup system working with a PVR-150 and Knoppmyth R5D1 (2.6.17-chw-8, ivtv 0.7.0), I placed one of the PVR-500 cards in that system, and put the other one in a Windows XP system.There's a little less snow using the PVR-500 on the Knoppmyth system, but still to much for decent viewing. The PVR-150 in the same box works perfectly. The system is an Intel 850 chipset (1.8ghz P4) with a matrox video card.In Windows the card works perfectly when using the 2.0.43.24054 drivers, but when I install driver version 2043_24103 or 20.43_24108(beta) from the Hauppauge website, I get the same snowy reception as in Linux.
This sounds like a problem with the firmware. I don't have time to go into how this is done but you need to use the ivtv source code to extract the firmware from 2.0.43.24054 and place that firmware in /lib/firmware.

Ok, I
replaced the v4l-cx2341x-enc.fw file with the HcwFalcn.rom from the 2.0.43.24054
driver set and that had some improvement--now one of the tuners on the PVR-500
works, but the other one still has quite a bit of static?
