I will dl the snapshot tomorrow (my brother doesn't have linux, and
I doubt I can convince him).

No, but I will do. Where can I find it. There doesn't seem to be one
on the quicktime4linux page, but there is one for libquicktime.

the qt one. but also mp3pro seems to be interesting, since a friend
of mine gave me some files with this format.

At first I will 'ida'-ize the codecs. :)
