add mp4 converter to the search right top of page.
I have several cd's that got stuck with itunes in locked mp4's / aac even though they are cd to itunes ripped in itunes when Itunes had this bug and now cd's is missing.
Aac+ is the default choice now for me 128kbs mp3 steaming in 24kbps to 32kbps aac+ and sounds better + takes up less space not sure about video maybe h.264 think in portage is ?264 or in the USE flags this can be added.http://www.di.fm
Wine door can install winamp or advertisement converter program as well , maybe burn the aac / mp4 files to cd-rw and then import them again or something not sure about video's.
or convert all of them to mp3 in windows and import to linux ?
Remember to uncertify or what is it called the pc itunes is on otherwise itunes has issues in future "account can not be used on more than 5 pc's" excuses.
Best of luck and post if you find something I can see many persons moving over might want to do the same.
