Last night when I went to render an .mp4, I got a message saying that my system had low memory and that I should close down applications...etc. I checked my ram-meter and I had 6 gigs free out of 8. Hmmm.

I loaded up Vegas 7.0 and tried to render the same AVI to .mp4 and got the same exact error message.

Can a codec just get corrupted out of the blue like that? I can render to any format (including mpeg-1 and mpeg 2) but not MP4.
