I have two Cinergy 1200 DVB-C PCI cards. I've noticed that sometimes when I record a program, MP fails to tune to a channel that belongs to a different mux. When this happens, TV Server configuration shows, that type of one of the Cinergy cards is "unknown". If I put my HTPC to sleep and then resume, PowerScheduler's reinitialize tuners -option seems to works as both cards are typically usable again after resuming.

I can't unfortunately provide at the moment logs but I've attached a screenshot of TV Server configuration.

I've upgraded to Vista and saw this same issue happening yesterday.
