I've used 3GP a few times to convert video to MP4 for my iPod video and it's been great. It's dead simple and performs wonderfully.

Lately however, it gets to 97-99% complete, gets an error, and then quits converting. I've tried downloading the latest version (034) and also tried it with a few different videos -- all with the same results. This is the gist of the error message that Windows gave me.

QT3GPPFlatten.exe has generated errors and needs to be shut down. Blah Blah Blah -- send error report, dont sent error report.

And here's the log from 3GP.

Maybe someone can make some sense of it?

Sorry if I've posted this in the wrong section. Any help is greatly appreciated.
