Subject: [ivtv-users] heavy snow/static on PVR-500 using ivtv .70 driver.
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.
I'd be
glad to answer any other questions. The following info is from the Knoppmyth
system:
