Emulator

What steps will reproduce the problem?

1. Load Dolphin
2. Load a game that uses .h4m movies. Dave Mirra Freestyle BMX 2 is the
   example I use, since it uses them for the intro movies
3. Get one of the movies to play.

What is the expected output? What do you see instead?
The expected output is the movie playing at the normal rate, with audio to
match.

The output is slowed down considerably, and seems to be somewhat variable.

What version of the product are you using? On what operating system?
JITIL 4771, Windows 7 x64 (I think I forgot to mention this on my other
issue)

Please provide any additional information below.
I first noticed it on r4771, but I suspect it came about with the sound
overhaul a number of revisions back. It still worked properly with r4525,
which was long before the overhaul. I don't really have the time to do my
own builds, and I know you guys don't like reports based on third-party
builds.
