Uh... What? A tuner is a tuner is a tuner, only accepts coax hooked to the 
coax tuner connector... I think you may mean "is there a way to tell the 
encoder on the PVR-500 to accept the input from the AV connections?". And 
yes, you can do that.

Er, can your DirecTV box output two distinct full-screen programs on different 
outputs at once?

Okay, maybe you were after a second coax tuner input? There's only one TV 
tuner input on these cards, the signal gets split to the actual dual tuners 
internally. You could do one on SVideo and one on coax with the card as 
shipped though, no extra piece from Hauppauge required. But again, that's 
assuming your DirecTV box can actually output two distinct programs at 
once...

Yes.

In theory.

The only audio paths into these cards are either though the coax connection or 
a stereo audio input, so I don't think so.

I'd have to guess you're not going to get 5.1 encoded audio, so no.

I think you'd better verify that a single DirecTV box can output two different 
full-screen programs on different outputs at once...

I'm rather partial to the 5.1 sound in all the HDTV programming I record. :-)
