In my case, the entir emenuing system was very slow, and setting:
  Option "UseEvents" "True" 
  In my xorg.conf.
  If it's really just the fade-in/fade-out that's slow, then I'd fiddle with the myth options on handling OSD playback.

It finally hit me that, although I thought I had XvMC enabled, I really 
didn't (thank goodness for the wiki!! 
(http://www.mythtv.org/wiki/index.php/XvMC#Tips_and_Tricks)). Anyhow, 
with XvMC enabled, my frontend systems play back the HD video smoothly. 
Of course, the OSD comes up in black-n-white, but I can live with that 
(still need to do the XvMC only for HD video adjustment).

However, when the OSD is up (let's say, it skips commercials and it is 
informing you of the skip), the whole playback comes to a crawl. It is 
as if someone put the speed at 0.1x until the OSD goes away and then it 
immediately starts playing at the normal rate. Is this normal (doesn't 
seem like it would be)? Or is there another step I am missing here..?
