I can play the sample TS file you've sent me with

	mplayer -vc ffh264 sample.ts

mplayer incorrectly chose mpeg12 in your case, as it doesn't expect
H.264 in the TS's PES packets.

Stock xine-lib-1.1.7 or higher can play those files. You may also want
to use vdr-xine-0.7.11 with a patched xine-lib-1.1.8 or stock xine-lib-1.2.

mplayer doesn't expect H.264 in PES files and therefore looks for a
MPEG1/2 sequence header.

BTW: Thank you very much for pointing me into the right direction
regarding this issue!

NOTE: be aware that FFmpeg doesn't support interlaced streams properly
at the moment. It typically crashes after a few frames. In my
xine-lib.patch for xine-lib-1.1.8 I've therefore disabled decoding of
interlaced frames (more or less properly).
