[MPlayer-advusers] [BUG] seek problem with external ac3 stream

Hello,
I encountered the following problem with r26205 and a lot of
earlier versions (though, I haven't perform regression test jet):
When I use external ac3 audio stream (-audiofile option), I cannot
seek in the movie properly: video is sought itself, but audio
stream starts playing from the beginning after the seek operation.
Moreover, video playback becomes becomes somewhat broken after
seek: it seems that fps became lower. Interesting than just
pausing (without seeking) works fine.
Video itself is ok and can be played without any problems, as well
as audio itself, but together they produce a problem. Such
behaviour is valid for any video in any container, but external
audio must be in AC3 format to reproduce a problem.
There is nothing special or uncommon in mplayer's output, but it is
provided at the and of e-mail just in case. Also I can upload a
sample stream, but this bug is reproducible with any AC3 stream I
have, so I can't see necessity of upload.
