Hold off buying HDMI cable
I'm glad I stumbled onto this discussion, I was just about to order a HDMI cable because my new Panasonic Plasma, only has 2 component inputs, and I have 3 component devices I'd like to attach.
The SA 8300HD PVR can use HDMI output, but after reading this I might stick to the component hookup and switch the Playstation 2 to S-Video.
SA 8300HD PVR - Component direct to plasma, audio to Yamaha
Pioneer DVD - Component direct to plasma, audio to Yamaha
Playstation 2 - S-Video direct to plasma, audio to Yamaha
I will do this for now, until I've read more. I only hooked it up yesterday, and watching the Montreal - Boston game in HD last night, was simply amazing.
