Can't burn OGG tracks to CD from iTunes
I'm sure this is related to the various other limitations imposed by Apple's closed API, but I thought I'd report it as I didn't see a ticket for it.
Basically iTunes won't burn OGG tracks to a CD. In a playlist with mixed OGG and other formats, iTunes skips the OGG files (they appear greyed-out during the burn process) and only burns the natively-supported files. Work around is to convert to AAC and then burn.
