I am asking the same question the guy with the 3rd generation Tivo is asking basically. Except i am wanting to purchase the toshiba HD-DVD player. If I have an HDMI hookup on my Plasma but not on my receiver can I just run the HDMI for my TV and the optical out for my audio on my receiver?? It definitely would suck if I had to buy a new receiver after having the hk 7300 for only 1 year. Thanks everyone for input.
