Hi I had a very similar problem with my PVR150 when I first started using it, went through all the driver changes etc and couldn't fix it, eventually found that if I used 'mplayer /dev/video0' things were fine but if I used MythTV this effect would occur. After a lot of fiddling with startup order between modprobe, mythbackend and mythfrontend (and stracing mythbackend and even hacking in the driver to add more diagnostics and disable various ioctls) I eventually established that a particular ioctl was causing this but only if VBI was enabled.
As it turns out, I had 'Teletext' enabled in Myth and hence the result. Turning 'Teletext' off has resolved the issue!!! I believe that /dev/video4 has VBI. so I suggest using /dev/video0 and see what happens. Good luck Daniel Previous Message...

One exhibits the problem I put online at http://trantor.org.uk/~roel/test.mpg, the other is exactly like the one uploaded by Christian. The thing I find strange about both problems is that the image is corrupted periodically, twice per second or so, and in-between these 'flashes', the image appears to look fine.
