It seems that the problem only comes about when I run mplayer svn with '-ao oss -afm hwac3'. If I run with '-ao none' or with '-ao oss' (ie playing 2 channel pcm out over the digital output), then the video plays back at the correct rate. Just to reiterate, all of those options work correctly with the version in ports - if only that supported vdpau :) Alexander, is this like anything you have come across before with the snd_hda driver? I have bootverbose logs of snd_hda if that helps[1]. Cheers Tom [1] http://pastebin.ca/1707268
