The new formats are about the quality of audio, not the number of channels. You can get 7.1 with them, but very few discs actually have 7.1 tracks because movies are usually mixed in 5.1 for theatrical release.
-How big of a deal is DTS HD? Are some discs coded in DTS HD, while others are in TrueHD?
There are three choices for losselss - dts-MA, TrueHD, and uncompressed PCM. They should all sound the same. But, since studios have their own reasons for the formats they choose, you need the ability to get all three.
-If I were to upgrade my speakers to 7.1, how would my DG910 handle source audio of 5.1? Would it only use 5.1 since I don't think the 910 does any matrixing?
Your AVR doesn't have PLIIx, DTS Neo:6, or DD-EX? If not, you'd be limited to 5.1, I guess.
Now, I am leaning torward the BDP-S550, although I may begin to research the PS3 becasue I am tired of waiting.
The PS3 looks like it would meet your needs every bit as much as an S550. The PS3 gets great reviews.
