[mythtv-users] Now it's just plain old jittery

Ok, I've defeated the X driver issue reporting bogus dot clocks. I made an
LD_PRELOAD library with XF86VidModeGetModeLine that returns a dot clock of 0.
But now it's still jittery. It seems to play fine for a second or two and then
pause briefly. The system is 80-90% idle though, I don't think it's having
troubling keeping up.
What's confusing me is this message:
2006-03-28 15:09:01.935 NVP: Audio is 3.25718 frames ahead of video,
doubling video frame interval.
2006-03-28 15:09:01.952 NVP: Audio is 3.7466 frames ahead of video,
doubling video frame interval.
2006-03-28 15:09:01.968 NVP: Audio is 4.23353 frames ahead of video,
doubling video frame interval.
Wouldn't doubling the video frame interval only slow down the video more?
Wouldn't that exacerbate any problem of the audio being *ahead* of the video?
Is this message phrased backwards?
