Hello all,

I had another try with XvMC last night and actually got a bit further 
with it. I'm only wanting it for standard defination playback, but as my 
system specs aren't great I'm hoping that it will help with occasional 
jittery/stuttery playback I get (especially on BBC1).

I have three questions regarding XvMC:

1) What's the best way to tell if it's working or not?
I find the frontend log confusing.
Times when I've thought that it is working, the fronend it thowing out 
all sorts of odd info.
Time when I've though it's not it's throwing out different info.
What should I be looking for?

2) Is it still the case that BOBx2 is the only deinterlacer that works 
with XvMC or is that old information (it's in the Myth guide I was 
looking at)
My previous de-interlacing preference was 'kernel'

3) The times when I've thought that I did have XvMC working, it's had 
kind of flickery lines at the top and/or bottom of the screen and and 
logos on screen look flickery. Is that normal?
Is XvMC a sacrifice in quality for the sake of speed?
I thougth it was just a speed increse.

It's frustrating that I spend most of my day at a Windows machine, which 
is where my email is set up for this list. It makes it so much harder to 
just send a few lines from the logs to enquire about.
