Yes, vdr saves its DVB recordings as PES to that .vdr files.
(according to http://www.vdr-wiki.de/wiki/index.php/PES)

Hmm, that seemed fixes to fix it in the first place. As I tried more files (with 
Audio and Video Streams), I found that streams are silently missing.
(Note the warnings from mpeg2video, maybe this has something to do with it?)

ffmpeg used to detect the contents (two streams) correctly in former times:

Currently all is fine, if I give "-f mpeg".
This even works if i pipe the data to stdin via
cat 0*.vdr | ffmpeg -f mpeg -i -

So this is no big issue at all.
