I can't be sure of the exact formats that you are asking about, however we have had very good luck with conversions using 'memcoder' - it is an open source program, part of a larger video/audio suite called Mplayer. It is a bit of a pain to get the parameters all right but for mass conversions, once done - that's it - just run a shell batch on all files. We run it on linux, but on the Mac OS/X will do the trick very nicely. since I am sure there is a port for the Mac. I've been offline so see this might have been solved, but wanted to add another option for those interested.
