Can you test out current CVS and see if that works for you?  I believe it 
should do the correct thing wrt this issue most of the time now..  and I 
believe I didn't break anything in the process, either =)

Actually, could you also test deleting an in-progress recording on a slave 
backend?  I had to modify the protocol there, and while I'm fairly certain 
it'll work, I'm not quite sure..  The machine I'm using as a slave backend is 
otherwise occupied at the moment..
