Onkyo makes a big deal about having "passthrough." A lot of people here have indicated they bought their Onkyo for that very reason so they could watch TV using the TV speakers without turning on the AVR and surround sound system.
Personally, I've never had any interest in doing that and my Sony ES AVR doesn't have passthrough so I've never needed to worry about this issue. The HTPC only sees the AVR. Seems to avoid a heck of a lot of problems that way.
I do think some other brands also have that passthrough feature.
