I have some channels I get some diagonal lines on using my Samsung PVR500. I thought it might be ivtv related, but I then loaded up Windows XP with the windows Hauppage drivers and noticed just about the same interference on the same channels. I have also noticed that the interference is better on some days and worse on others. This is leading me to believe that it is more signal related between my cable company and the computer hardware/PVR.
I am also still having the sound issue where sometimes when I tune in a channel I just get loud static that goes away when i change the channel. It seems to be related to the tinny audio issue as the same things that help the tinny audio problem seems to help this one as well. It is to the point where it happens maybe once every 50 channel changes/recordings, but still a little annoying. I know I could run one of the scripts that are out there, but I have been lazy about that. I am running an evil VIA chipset that works well for the most part as long as I don't use IVTV and the onboard ATA controllers, otherwise I get the classic random rebooting problem. However, I am going to replace it with a SIS748 chipset in the next week to see if that helps any of my minor issues. 2 cents, Doug On Sep 6, 2006, at 5:20 PM, Michael Gebis wrote: > Since nobody's answered your question on the mailing list yet, I don't > feel bad offering up my wild guess: Is it possible there's a grounding > issue?
