[mythtv-users] Shouldn't XvMC be faster than Xv?

I'm running SVN 8625, on a P3 1G, 512MB RAM, GF MX440, and non-HD video 
with XvMC works flawlessly for me now. I used to have to enable 
deinterlacing, but I tested last night and it works great now without 
it. No hiccups at all. I have the following options enabled (that I 
recall from memory)

- extra audio buffering
- standard xvmc
- opengl vsync ON
- use video as timebase OFF
- no deinterlacing

I think HD would probably be possible with my setup, if I had any HD 
material... :)
