Whatever I try, I am not able to play the TS capture. But that's not a 
big deal.

Yes, I have now tried with the current xine-lib (1.1-branch) from 
mercury and I can actually play the 001.vdr file. Nice! Yesterday I just 
hastily tested with mplayer.

You are very welcome, since your h.264 support for VDR is greatly 
appriciated :)

Xine does not crash, but the playback is really slow and there are 
"ghost effects" in the picture. Xine puts out this kind of messages all 
the time:

[h264 @ 0xb61168f4]concealing 6960 DC, 6960 AC, 6960 MV errors

ffmpeg_video_dec: error decompressing frame

I have an Intel Core 2 Duo E6300 (1,83GHz) which might not be enough. Do 
you have the xine-lib.patch for disabling interlaced frames available 
for download somewhere?
