Great to know.

I simply increased the size of the video buffer so it's more tolerant
when you have a big delay between audio and video.
This mod was required with HD-PVR which has a big delay between sound
and video frame.

You get those errors if you have -v playback active ;
but is the sound okay ?

I've seen videos that do show those errors, yet they play fines.

you can download the source packages of my repository.

The last one being:
http://www.avenard.org/files/ubuntu-repos/files/mythtv_0.21.0+fixes-20450-openglvdpau-0ubuntu3.tar.gz

Here you will find the original source file ; the list of all the
patches are in debian/patches
the list of the patches applied are in debian/patches/00list

If compiling on 8.10 ; make sure you don't install the 30_python patch
; it's for python 2.6 that comes with Jaunty
