#381 closed defect (invalid)

jerky DVD playback on amd64 + GeForce 6600

Mplyaer plays DVDs with jerks and pauses (dropped frames?). Xine plays the same
DVDs correctly. Tested on Mandriva 2005 LE and Gentoo 2005.1. Used 1.0pre7 and
the latest CVS versions.

The problem does not depend on DVD drive (tested with DVD-image from HDD --
problem persists) and occures with both "nvidia" and "nv" video drivers.

Using 6.8.2, module XVideo loaded.

First word in description should be "Mplayer", of course :) Sorry for typo.

Please provide a full mplayer -v log. Also, have you tried the -cache option?
How about -vo null? How about -nosound? -srate 44100? -srate 48000? -vfm ffmpeg?
What does the "(dropped frames?)" part mean? There is a dropped frames counter
in the status line, so you can see that (though MPlayer never drops frames
unless you specify -framedrop or -hardframedrop).
And it's MPlayer, not Mplayer.

Sorry for delay. I've tested it a little bit -- it really looks like
sound-related problem. At least, -nosound gives very smooth playback without any

I used ALSA compiled in kernel (not as module), now recompiled kernel to set up
ALSA as module. It partly helped -- now playback with sound is nearly OK, but
not so smooth as in Xine. I'll try to manage it by tweaking ALSA.

Closing this.

Thanks a lot!
