Is there something wrong with 2.511? I'm trying to frameserve from AVISynth, and encode to MPEG1 with 2-pass VBR. I don't seem to get the error when I choose something other than 2-pass VBR.

I have plenty of space on the hard drive, and just defragged them, so this seems like more of a bug, but very frustrating because *sometimes* I can encode in 2-pass VBR without getting a stream writing error.
