Using totem-0.99.11 with gstreamer/gst-plugins 0.8.1, i'm having issues with A/V
sinking after seeking/pausing a video (seeking/pausing display different problems).

My setup:
using xvimagesink and alsasink device=dmixed where "dmixed" is defined in
/etc/asound.conf to use the dmix plugin.

When first starting the video, audio and video are perfectly synced. Two
different problems show up when manipulating things:

Seek: After seeking to any other location in the video, the video stream seems
to be lagging by 1/4 to 1/2 a second behind the audio. When playing the same
video using esdsink, the A/V stays synced fine (although the video is
consistently jumpy with esdsink (thus me using alsasink)). Confirmed that this
same sync issue exists when using device=hw:0 directly. I also don't think dmix
is to blame, as mplayer can play multiple streams to dmixed and have no syncing
issues. 

Pause: After pausing a video, and resuming playback, the video shoots of at
about 3x speed and the audio stops altogether. Sometimes, things get restored
after it zips like this for a few seconds, other times it continues on
indefinitely. If using device=hw:0 instead of device=dmixed, then resuming from
a pause just doesn't work at all, and hangs there.

alsasink+dmix seem to be really nice (using muine and totem together, etc, etc)
in general, but i can't really use totem with the gstreamer backend until the
A/V is consistently synced.

what other info do you need from me?
