That helps, but still no dice.

Visduh (running under VMware Player 2.5.2) accesses a (commercial) data 
disk flawlessly, regardless of hal polling (on the Ubuntu host) being 
enabled or not. I suppose that's because Ubuntu doesn't know what to do 
with it, so it does nothing with/to it.

I'm unable to access a (commercial) audio CD though. I tried stopping 
hal on the Ubuntu host, and that made things worse, as Visduh would 
hang. With hal running and polling disabled, Visduh acts as though 
there's nothing in the drive.

/var/log/messages gives this hint (repeatedly) when trying to recognize 
the audio CD:

I've tried various audio CDs with the same result.

Anyone have an idea? I've googled and found this error in other 
situations, but none so far with VMware player (which works fine with 
data, just not with audio CDs).
