I'm posting this now on this list, because got no reaction from dvb-list.
I noticed a weird problem with last weeks Mythbusters episode VDR recording. The playback suddenly speeded up like fastforward and it is repeatable. I've seen this once earlier also, but thought that it was caused by bad reception, but this time the were no visible errors on the recording.
Here's the clip (22MB): http://kotisivu.suomi.net/izero/mythbusters.tar
Tested with VDR 1.4.5 and firmware versions 261a, 261f, 2622 and F12623 testversion (normally in use). Not repeatable when played with VLC on OS X.
