Not sure if this helps but I use my pio bdp-05 bluray player as the decoder for the true DTS-HD audio and run the analogue cables to my CJ multi channel pre with great results.
One of the pleasant surprises for me has been the astounding audio improvements with the new formats.
May want to check which formats the bluray player will decode, ie master dts-hd.
As far as 1080i vs 1080p, depends on your tv size.
With my 60" Pio 151 plasma I get direct tv hd in 1080i and it's very good, but the 1080p is better with bluray player.
Tho over time I tend it take it for granted.
hope this helps some.
