Band-in-a-box on OS X?

[Squire]

I'm interested in PG Music's Band-in-a-Box program but I'm concerned about it not running well on OS X. Their site recommends that you run it on OS 9 because it "may have timing problems using QuickTime" in OS X.

Can anyone verify this? Or, better yet, is their a similar program that runs well on OS X? I'm looking for some kind of accompaniment program.

Thanks a lot.
