@Masquerade :
Srep+razor : whats the point ? Razor already dedups the data ! Use LOLZ instead of RZ. It compresses much better.
Mp3 : use MPZAPI with PMT. Much faster than MSC.
Use MSC when MP3 files are embedded in other files(stream).
BK2 : some bk2 files cannot be processed as bink with BPK (corrupts the archive). Compress them separately to check things.
Hope this was helpful.
