Hi,

I'd like to revisit this problem that was posted 13th March.

1. I looked in the latest MPlayer release but couldn't find anything
    referring to fps in vo_mpegpes.c (anymore)

2. If it's not a problem of the DVB cards - i.e. the DVB cards can
    replay 30 fps - would it be possible to figure out the fps of a
    video and set this accordingly at runtime?
    If a runtime solution is not possible, how about creating two
    binaries (e.g. mplayer25 and mplayer30) and switch between these
    depending on the video (e.g. from a script - but how do I get to
    the video's information first to figure out which binary to call)?

Regards,
