Correction: it actually shows some problem with the stream at the 
beginning (may be due to the editing done by vdr) but it recovers 
gracefully after that, contrary to xine.

These are the messages by vlc:

decode_slice_header error
non-existing PPS referenced
decode_slice_header error
no frame!
number of reference frames exceeds max (probably corrupt input), 
discarding one
mmco: unref short failure
mmco: unref short failure
mmco: unref short failure
illegal short term buffer state detected
