Fraid I've never used VDR, but I'm guessing what you're doing is setting up a fake DVB-style device so it'll read in the transport stream. Have you tried just catting directly from /dev/video1 and playing that with mplayer/xine to eliminate VDR as the problem - I know its unlikely as you say running it in 2.6 breaks it in 2.4 as well - and you've probably already tried that anyway. Is the saa7134 definitely picking up the correct card type? I had some problems with 2.6.8.1 initially 'cos I'd forgotten that 2.6's module tools have a different file for specifying module parameters in. Mine (now) shows up in dmesg as "BMK MPEX No Tuner" for card type 18. I don't have an MPEX with a tuner right now - do you? maybe that is the issue... I tried lots of things to see if I could get it to drop audio - unplugging cables and leaving them out for a while etc. To me, stability actually seems to have actually improved as video now restarts properly if I unplug and replug the video stream, no matter how long I leave it, or how many times I do it. The machine I'm testing on has a very minimal set of audio drivers installed - its just got soundcore compiled as a module and nothing else.
