[Mplayer-dvb] a/v sync mencoder with *.vdr files

[Martin Hoffmann]

Now it's on its way !
It's around 400 MB 001.VDR Recording of StarWars Episode 6
For sync issues you should check time index ~320 (c3po knocking on door) and
maybe ~916 (thermal detonator activation, and some guys speaking in foreign
language, sometimes you can watch for lipsync - for Jabba i guess you cannot
tell :-))
It will at least take 7-8 hours from now on, because i can only send with
128kbit :-(

Ah  ! Its found in /MPlayer/incoming/mho_avsync/new/001.vdr

Do you need some additional information, or a file encoded by me ?

Martin.
