Video (panned fast) goes for a toss

I can tell you what is happening there.  The fast panning is causing the
video + audio encoding cpu utilization to be greater than the XO 1.75 can
schedule.  With the current 1.75 codecs the audio capture and encoding
takes quite a bit by itself, and after you do a fast pan the theora encoder
has to work much harder trying to match the encoded video with the audio
trying to keep it in sync.  It is just not able to do that and is thrashing
trying to figure out where to keyframe and sync at.  We have optimizations
in the pipeline that will make the xo 1.75 a more capable video capture
device.  Please file a ticket so we can keep track of this issue with you.
