Wow, can't believe how frequently our A/V systems change!
My 04 came with the plasma, vcr tuner/player and dvd player.
Sound was connected from the plasma tv speaker output to a Riverpark "DHS" system, which powers 5 speakers and a sub-woofer.
I replaced both the DVD and VCR with a Samsung combo DVD/VCR with progressive scan and component video output. ($99 at costco)
I also used an older Dishnet 6000 HD receiver (ebay ~ $100 or lease for $5/month --plus $5 month activation fee).
I connected both of these thru a component video switch to the plasma.
I have fiddled with the basic controls on the plasma, but haven't dialed it in just right yet. It has advanced pic controls and I'll check that Avia guide; thanks!
