Some great posts here from the usual suspects
Quick, slightly related Q: With Bluray and or HDTV what will be the standard resolution for movies? 720p or 1080p? Currently my projector is a 720p native LCD..I only bought it last year, and would be hesitant to replace it so quickly, but a replacement next year could maybe be on the cards if 1080p will be the standard with these formats. I'm not so concerned about 1080p games, but if the movies are there too, I'd be sorely tempted.
Also KLee - with dts-HD, Dolby Digital Plus etc - there are receivers out there at the moment that support these?
Thanks..
With both HD-DVD and BRD, the movies will be authored as 1080p on the disk itself.....this resolution is the same as film, which is 1080p/24.....well....actually its 23.98 frames per sec on film, but who's counting
Depending on the HD-DVD/BRD deck, you will have the option to perform all the deinterlacing and ( in your case) scaling either in the deck itself and then passed to your TV as 720p via HDMI..
OR
The raw 1080p/23.98 signal will be passed digitally via HDMI and then all scaling and frame rate conversion will be handled within your tv (unless you have an expensive outboard scaler, this would be the best option)...
OR
You might find a deck that gives you the option to do both (either scaling/frame rate conversion/deinterlacing at the source deck or the display itself via HDMI)
BTW, all this stuff also applies if you only have DVI+HDCP ins on your LCD TV as you can just use an HDMI (female) to DVI (male) converter for about $14USD...so no worries there
OPTION #1
Both Dolby Digital Plus and dts-HD are similar in that they are backwards compatible.....a Blu-ray or HD-DVD movie encoded in either DD Plus or dts-HD will be downsampled to regular Dolby Digital 5.1 or dts 5.1 output through the S/PDIF connector (either toslink or coaxial audio) on the BRD/HD-DVD deck to the reciever which "sees" the data as regular dts or Dolby Digital (in the case of DD+, the downsampled Dolby Digital 5.1 is played back at the max 640Kbps data rate.....no Laser Disk, DVD or even D-Theater movie released ever used this max rate)
OPTION #2
Now, if you want to hear the full res versions of Dolby Digital Plus, Dolby Digital Lossless (MLP) or dts-HD you will need to have IEEE 1394 firewire/i-LINK or HDMI ins on that reciever....
HOWEVER
Keep in mind, HDMI v1.0 and v1.1 will *not* be able to pass a full DD+/DD Lossles/dts-HD audio signal....for this you will need HDMI v1.2 or better (you can also pass SACD audio with this version).....the only recievers that I know that are upgradeable to HDMI v.1.2 are the Yammy RX-4600 and both the Denon AVR-4806 and the super expensive Denon AVR-5805.....all three are only HDMI v1.1 but upgradable via firmware update due in the fall.....the reason for this delay is because its an AACS encryption issue on both HD DVD and BRD, but you didn't hear that shit from me...
Although these are all expensive recievers, Zoran, Silicon Image and Sigma Designs are no longer producing v1.0 or v1.1 HDMI transmitter/reciever chipsets so all the upcoming A/V recievers with HDMI switching(yes, even the cheap ones) should be DD+/DD Lossless and dts-HD compatible for those HD-DVD/BRD Player/Recorder and PlayStation threes......
One thing to note that HD-DVD products and BRD products will not output the same quality audio.....for example,the max bitrate for DD+ on HD-DVD is 3 Mbps, and on BD it is 4.736 Mbps.....just wanted to let you know that
Here is some info on the upcoming audio codecs, for those who are intrested

Also, I had a personal demo of Dolby Digital Plus and can go over its inner workings here, if you wish
