Hi Max!

Good to hear from you :).

Did you try to use the same data files on your desktop machine? Do  
they work correctly there?

Ah, you are so modest to leave out
   c) We broke something in the vorbis code during the recent  
refactoring ;)

Anyway, if Ogg works fine with the same files on a desktop machine,  
and for everybody else, then c) is not so likely. But for now, I  
wouldn't rule it out. Did anybody (esp. porters to other "exotic"  
platforms) try out Ogg Vorbis support in SCUMM .bun files recently, I  
wonder?

Well, Ogg in .buns means we are using a subsection of a ReadStream.  
Maybe the Ogg Vorbis decoding code has a regression with regards to  
that, while the MP3 decoder hasn't... :-)
