I've checked your recording. Lost "The other 48 days" - surely one of 
the worst episodes for me too, because the fade-to-black on every day break.

Your recording however runs relatively fine on my FF (r1.6 firmware 
f22623) card. There's noticeable audio stuttering after the 
fade-to-black scenes, but audio desync is only small, though noticeable.

Demultiplexing with ProjectX throws 11649 of errors like this:

!> error in pes_extension of pes-ID 0xE0 @ pos: 38780 (2048 / 14 / 15 / 
true / false)
!> error in pes_extension of pes-ID 0xC0 @ pos: 46972 (686 / 14 / 15 / 
true / false)

pos is changing, the rest seems always the same.

I then re-muxed the elementary streams and converted them back to VDR, 
and the resulting video played fine again. So this issue seems to be 
some problem on the PES packaging layer.

In contrast, my recording issue cannot be fixed by re-muxing, and has 
more noticeable audio desync, its probably a totally different issue. 
The dev's already have a sample file.
