Honestly, if you have MPEG Layer 3, just use that, I doubt Lame is going to make much difference...

Ok here's my latest findings:

I took the Delgo QuickTime trailer, and converted it to a 38.9mb DivX file for the desktop. (I cranked up the bitrate really high for the desktop version, that's why it's so huge.)

Then ran it through VDub again for 2 PPC versions.

v1) 250kbps DivX and 128kbps stereo MP3, left at the original 24 fps. On the Axim, the audio did get out of sync, but less than a second. I'm guessing that even at those bitrates and framerate, the video is still taking too much CPU and the audio decodes faster. File size: 7.82mb.

v2) Same settings, but decimated the framerate by 2. Surprisingly, even though 12 fps sounds low, the playback on the Axim was just fine, and it stayed in sync perfectly. File size: 7.73mb.

-----------------------

I also noticed that VirtualDub is up to v1.5.4 now... I just upgraded mine.

-----------------------

On the issue of VirtualDub getting livelocked at 99% on Job 2: this is hardly a definitive solution, but I have noticed that it tends to only happen when I'm only processing audio on Job 2. If I process audio on both jobs, VirtualDub seems to complete just fine...so far.
