This particular version of Mplayer exhibits a bug wherein the video playback freezes at certain scene cuts on a DVD. Audio continues, but the video freezes for a number of seconds. Then the video rapidly catches up to the audio, but then audio stutters for a while. A short while later, everything is fine again — until the next problematic scene cut. This bug does not present itself in media-video/mplayer-1.0_rc4_p20100506 (the previous version in Portage) or in media-video/mplayer-9999 (currently r32382). It appears to make no difference whether I have KWin's OpenGL compositing enabled or whether I'm outputting raw AC3 via S/PDIF or decoding it in software and outputting PCM. Also, it makes no difference whether I use the ffmpeg2 video codec with the xv output module or the ffmpeg12vdpau codec with the vdpau output module. The problem is 100% reproducible at certain scene boundaries. I am guessing there must be a VOB Cell boundary at these places because the A/V timestamps shown in Mplayer's console output reset to zero there. There are at least two dozen of these problematic scene boundaries in a typical movie. I have experienced this problem both on TV shows (with mixed NTSC and film framerates) and on high-budget movies (pure film transfer). Also, it makes no difference whether I'm using the pullup video filter. A workaround for me is simply to go back to the previous version, media-video/mplayer-1.0_rc4_p20100506, which powers through these troublesome scene cuts without missing a beat. I know this is not a Gentoo problem, but I wanted to register my issue so that p20100612 will not be considered for stabilization.
Just for kicks, you're not using -cache are you? -nocache needs to be enabled for DVD playback. Thanks for the bugreport otherwise.

Here's my ~/.mplayer/config: ac=hwdts,hwac3, softvol=1 stop-xscreensaver=1 vo=xv When I play a DVD, I use the following command line: mplayer -xy 2 -dvd-device DVDs/foobarbaz.iso dvd://1 I throw in a "-vf pullup" if the DVD suffers from hard telecine, but that's it.
