In thepast I have already tried to figure out why the driver's play_iframe()
function works with frames from the driver developers and apparently also
with frames from other sources, but not with the ones created by VDR.
There must be some tiny little difference that causes this behaviour, but
I just can't find out what that could be.

If somebody with a deeper knowledge about MPEG formats could take a look at
some frames that work with play_iframe(), and others that don't (derived from
a VDR recording), and could tell me where the difference is and what VDR could
do about that, I would highly appreciate that...
