Well I've got DVBviewer working just fine now. However, I notice that periodically I get picture corruption. This happens only once or twice per minute or thereabouts and so far I've only really noticed it on TV1 (which to be fair is what I have watched most so far). I can best describe it as a pixelation effect which seems to happen around edges in parts the image. I would hazard a guess and say it may be related to the Mpeg4 decoding.

Has anyone else experienced this? I'm not sure if it is related to my system or the transmission. It may be a heat related problem in my passively cooled 8500GT GPU which tends to get a tad hot (like early 80's) after a few hours. The GPU is doing thr H.264 decoding.

If the problem is happening right from system boot I would doubt thatit would be heat related. It sounds like a possible signal strength issue me - how far are you from a transmitter and what sort of condition is your aerial & cabling in?

To be honest, I didn't notice this at all until I sat down and watched TV for an extended period and then it only seems to happen after an hour or so. In all my tests (mostly looking at the Freeview demo channel) I didn't see it. Also I've only seen it on TV1. More tests are needed. I just wanted to check whether this is a common problem.

Signal strength is fine I think. What is the best way of verifying this?
