[theora] Impossible to encode this file in sync

[®om]

Hi all,

I am unable, using ffmpeg2theora 0.26, to encode this mpeg file in
theora without audio/video sync problems :
http://dl.rom1v.com/noindex/test.mpg

The file works correctly using vlc or mplayer, but totem has sync
problems for playing it.

For information, it is a TV stream I recorded using :
vlc "rtsp://mafreebox.freebox.fr/fbxtv_pub/stream?namespace=1&service=201&flavour=sd" ":sout=#std{access=file,mux=ps,dst=$out}"

(don't try, you won't access this URL, it is accessible only using
"Free", one particular French provider)

If you have any idea…

Thank you for your help.
