Hmm, OK, well I tried this card in my other PC which has a nasty via chipset and dual P3 processors, but a 2.4.20 kernel, and after playing just a single channel (without sound) it appears that things are OK there. Obviously would need to check a couple of channels and sound sync to be sure everything was absolutely fine, but, it does suggest a hardware issue with my p4p800 based machine... (ie the original machine which wasn't working)
So, ripped out the 2.4.22 gs based kernel and tried a 2.4.22-ac kernel instead (I seem to need a post .21 kernel to get the hard disk and other hardware supported). This works "better", in that now there is no picture breakup at all, and mplayer is not complaining about broken frames, etc. However, the picture is now jerky, it plays smoothly for a few frames, then hiccups, then plays smooth for a bit longer. Appears to be 1-2 hiccups a sec giving a kind of jerky progress to moving objects. Sound is out of sync as well. However, some channels do now seem to be OK. This was just a two minute test, and overall the -ac kernel does not seem to be acting very responsively so there could well be something else going on. Will try it with mplayer on a normal video file, etc to check that it isn't something generally wrong with the new kernel. I guess after that I need to start disabling the onboard hardware and see if I can't get this card working. But assuming that it is some kind of corruption on the PCI bus, then are there any tips on debugging this or preferably making things cooperate. I tried bumping up the PCI latency on the dvb card to 128, however, this didn't appear to make any real difference... Guess it's back to fiddling Just for reference this is an Asus P4P800 board. I don't suppose that anyone else has one of these and could say that it works for them with a budget card? The full featured card works fine... (well apart from crashing frequently...)
