my new Sony BDP-S550

[Yellowjacket]

Just got my BDP-S550. Went to Circuit City this evening and picked it up. Didn't have a lot of time to fully set it up. Only getting video signal right now no audio. I have an older TV with the Sony connected via HDMI to DVI input. I assume the TV's DVI doesn't carry the audio signal and I'll have to run separate cables to get audio thru the tv speakers??
I still have to run speaker wires under the carpet to hook up my surround sound. I have an old Onkyo HT-S520 6.1 receiver. I will probably end up updating that sooner than later too.
I put Transformers in and just watched the so see the picture quality. It IS better than standard DVD but I was not blown away by the blu-ray experience. My wife is gonna hate when I want to get rid of the old Hitachi projection 1080i dinosaur (4 years) and go with a shiny new plasma or lcd.
I'm not a diehard audio/videophile but I do want a much better picture than I am currently getting from this TV.
