Well, I remember there was a thread even this year in which Klaus was
admitting he should make this configurable after version 1.4 is polished
http://www.linuxtv.org/pipermail/vdr/2006-April/008726.html
The attached patch was sent by C.Y.M. by that time, and looking to it,
it seems it could make a difference, as it hard-codes the frame rate in
recording.h among other things. I just tried if it cleanly applies to
vdr-1.4.1 and it does, so give it a try.

Your old PAL recordings may no longer play OK after this patch, but I
think it's worth a try, just to narrow down the problem.

Yes, and don't forget that "Frames per GOP" setting, maybe that one is
important, too. In the end maybe it starts working with both of these
patches.

Cheers,
