well, i got my today.
First impressions, just out of the box, power it up, connect to onkyo705 using hdmi and pop in iron man... no setting changes.
1. packing was horible- no fedex package, just the sony s550 box, box already torn at the bottom.
2. No new lights show up on my 705. I already watched sd-dvd of Iron man, and i watch movies in PLIIx mode(i have 7.1 setup). With the BD version of Iron man, it changed to multi channel. Sound wise i (think)did not hear any difference between the BD and SD disc. Picture wise, BD looked a little better.(definitely not worth 423 dollars).
3. Popped in Sd dvd, my philips dvp5982 did a good job with the picture than the s550, i thought, this is again just 5-10 minute watching.(i just got the player an hour back!!).
Will try to read the s550 manual and the onkyo 705 manual to see if i need to change anything for the BD player to get maximum of out it.
Don't flame me, as i did not do any adjustments. I sure can take some suggestions to improve the sound quality if not both pic and sound.
