Default HD-A2 Audio Question

I just got my Toshiba HD-A2 today. I have the audio bitstreaming though an optical cable. The weird thing is that on my reciever it says DTS, but Transformers is in Dolby Digital. I have a Pioneer VSX-516 reciver, planning to upgrade to an Onkyo 705.

Also I'm using an HDMI to DVI cable, in resolutions I select "up to 1080i" but it keeps displaying in 720p.

I just gave my 360 add-on player to my friend. When I used the add-on Dolby Digital appeared on the reciever. But I should get DD+ with the Onkyo 705 when I soon buy it.

It's diplaying 720p because that's what your tv is outputting unless you happen to have a crt. All 720p lcd and plasma tvs take the 1080i signal and output it as 720p which is the equivalent (to 1080i) on a non 1920x1080 diplay(in other words a 720p display).
lcd and plasma display utilize a progressive scan technology so interlaced signals are displayed progressively.

Sorry, Arkadin, this comment on resolution is incorrect. All HDTV LCD and plasma displays do not convert 1080i to 720p.

Most good 1080p capable displays upconvert 1080i to 1080p because LCDs intrinsically display progressive. It won't be as nice as full 1080p source, because there is less data, and any form of interopolation is subject to motion artifacts, etc.

The only display that will always convert to 720p is a 1280x720 display. This CNET article explains this in lay-terms. Dogmat doesn't describe his display, but it's probably a 720p display, not 1080.

Also, dogmat, if your receiver has any hdmi capability, feed it PCM through HDMI, not through Toslink or coax, then you'll get 24/96 audio, not 16/48.

Like I said on NON 1920x1080 sets (Lcd or plasma), the set will show a 1080i signal as 720p. So I was talking about native resolution 720/1080i sets. Right? On these 720p lcd or plasma sets, the interlaced 1080i signal will be diplayed as a 720p progressive signal. That's what I was trying to say. Sorry if you misunderstood me. I have edited my post to make it clearer.

Ah yes, violent agreement. I didn't read the original post that way, but then again I'm cross-eyed tired. So why am I writing instead of sleeping? Good question. Doh!

I have 720p DLP. It did 1080i with the Blu-Ray movies on the PS3 when I used DVI, but I can only get 720p with the HD-A2 when I use HDMI to DVI. I'm using component cables now with the HD player and I get 1080i just fine.

My reciever doesn't have any HDMI ports, but I'm planning to get a new one before Christmas. Anybody have some good recommendations. I'd like it have 7.1 sound and be able to play TrueHD and DTS HD.

Since your TV's resolution is 720 you should set the HD DVD players output to 720P. Always match the video output with that of the TV.

As for receivers, since you specifically mentioned DTS HD you will need to look at the new ones from Denon, Onkyo, and Pioneer as they should be able to decode a DTS HD track if your player supports bitstream audio. All three brands are good and everyone has an opinion on which one they like. Just look over the offerings and find the one that offers the most features in your price range.
