[mythtv-users] Nvidia VDPAU

[Simon Jones]

Sounds like you are getting "prebuffering pause" errors.  But I'm sure
you already know all about this issue because it has been posted on
the development list for weeks.  And you are reading the development
list right?  You need to if you are going to run unreleased code (such
as VDPAU).
----------------------------------------------------------------------------

ok, I have set the buffers to 32 (after a bit of research).

it's improved things, but i still feel like there's an issue, so am going to list some bit's out of the logs to see if people say it's normal or there maybe a little issue! Is it waiting for the sound and then dropping a frame or pausing, or is this below normal?
