Ever since the new version of XBMC, I've had a slight out of sync problem (XBMCFreak version). I've tried a few things like sync playback to display, but no use. It's literally like a few milliseconds out of sync on everything. It's installed on a Acer Revo, going through a home theater system via HDMI. I could manually fix it in my home theater receiver, but it would make the other things connected to it out of sync.

I'm not really sure what else to try, so any help would be great.

edit: should add that it only seems to happen with SD videos
