CSS movie issues..

[bigxman]

I play counter strike source. I got this really nice clip of me shooting down the whole other team in an esea pug. This is how i did it so far:
playdemo "whatever the name was"
demoui (fast forwarded to the part where i wanted to record)
got the anX movie cfg, removed hud, crosshair, and everything but the video and gun.
host_framerate 90
startmovie scrim
endmovie

then I have a bunch of .tga's in my cstrike folder. I put the first one in Virtual Dub, and the whole sequence popped up. So i just made the framerate 60, made the color depth 24 bit RGB, and didn't compress it. Then I save as AVI.
If i open up the AVI with Windows Media Player, it's the raw (obviously), clip, and it's perfect. Just a little slower then normal, but other then that no frame skips or anything. Runs smooth.
When I edit, render as .wmv with the youtube HD template, the video is choppy, 15 or more frames are being skipped.
Even when i don't edit it, and just rended as .wmv, it doesn't work.

What am i doing wrong?
Thanks.
