I can't remember if you're compiling from source or not, so this may not help:)

The attached patch may help - it's not perfect (it doesn't work 100%
of the time and it will wreak havoc playing progressive scan content).
It's against the mythtv-vid branch but shouldn't have any issues with
other/older versions - and the important stuff is only a couple of
lines.

With this in place I get perfectly smooth/synced playback at 1080i
most of the time - still trying to figure out if I can get 100%!

I'll explain it in more detail when I've had some sleep.

Regards

Mark
