Converting mov to m2t for Sony Vegas

A friend captured from a Z7 with some Apple-flavour software (I think it was FCP). That's what in the mov:

The streams themselves are completely compatible with Vegas but the container causes problems because it loads the quicktime DLLs and they won't like mpeg2 for some reason. Essentially not a Vegas problem but an Apple problem. I decided to convert to m2t with ffmpeg:

ffmpeg -i Boots.mov -vcodec copy -an boots_noaudio.m2t

Note "-an" means no audio. With audio added to the m2t file Vegas 10 locks up. I guess ffmpeg is not generating a fully compliant m2t file. Instead I exported the audio as separate tracks:

ffmpeg -i Boots.mov -acodec copy -vn -map 0.1 boots_audio1.wav
ffmpeg -i Boots.mov -acodec copy -vn -map 0.2 boots_audio2.wav

...and loaded the 3 files into Vegas and then grouped them.
I had quite a lot of problems with ffmpeg generated files but this workflow works at least and there is no loss through recompression.
