Comment:

 Ok, it looks like there hasn't been any spike in CPU usage. If the you are
 using OpenGL VSync with the framerate matching the video frame rate, then
 video frames are getting dropped simply because your audio device is
 playing the sound more slowly than it should.

 Since you've use video as timebase, and have extra audio buffering, then
 the next thing to do is install a new sound card. Unfortunately, this type
 of hardware issues are pretty much impossible to fix remotely.

 FYI If you use bob-deinterlace the dropped frames should be less noticable
 unless an OSD is on screen.

 [marking as invalid, broken hardware].
