[vdr] Re: Resampling Audio with mplayer cause choppy sound

["Marc Lentwojt" <m.lentwojt@f-h-c.de>]

I think i`ve found the problem. The debugging output from mplayer says:

Jan 10 20:28:39 linux logger: *** DEBUG: OutputFromMPLAYER:
"ID_FILENAME=/movies/findest.wmv ID_VIDEO_FORMAT=WMV2 ID_VIDEO_BITRATE=0

The entry "ID_VIDEO_FPS=1000.000 " is very strange. So mplayer thinks,
this movie has 1000 fps ? No wonder, that -speed is unusable, isn`t it ?

How can i change this behaviour ?

Thanks
