[Mplayer-dvb] Stuttering video and audio when playing DVD

[Lars Fredriksson]

Hi!

I'm trying to be able playing DVD's with mplayer and viewing it on my TV using my Nexus-S DVB card - and it works fine as long as I don't want to show the subtitles ... beacause as I've understood I've need to use the '-vop expand' parameter to activate the OSD - and then the video & audio starts to stutter.

I really don't want to change the size of the video, just activate the OSD.
I'm running it on a Athlon XP 1800 and Gentoo 1.4 - I've tried both the mplayer package that comes with gentoo and the latest from mplayerhq.hu - same result.

Tha last parameters I've tried with was;

mplayer -dvd 1 -slang sv -subpos 60 -vop lavc=9000,expand=-1:576:-1:-1:1,scale=-1:0,dvbscale -vo mpegpes

And that don't work so good ... I don't think it's the DMA or something like that because I can use the DVD-plugin for VDR - but with that I get errors with other stuff like the menus and so ;-)

Anyway - anyone that have an idea what this can be about???

Any help would be really appreciated!

Best regards, Lars Fredriksson
