Blu-ray uses MPEG-2 and H.264/AVC. A 10-bit "uncompressed" 720 24fps 2 hour film clocks in at around 400GB. A 1080 project (which is what many people are shooting on now) can clock in around 900GB. That's the size of the final master file in those formats, as perfect as they're going to look. Now those pixels get crunched down to 25GB for an HD optical disk. For AppleTV they get crunched down to 2GB (? still not sure exactly). Trust me, there's no overkill. Even a Blu-ray disk does not compare to the original. Post facilities should offer guided tours so that people can sit in a finishing suite and see what a true HD signal on a $25,000 professional monitor looks like. It is truly amazing. Go to NAB and check out some demos. It makes your HBO HD look like VHS.
Blu-ray also uses VC-1. As for file size. It usuall take me about 15 minutes to DL DVD-quality rental from iTunes. That ≥480h resolution at ≥1.5Mbps. The HD rental I purchased took almost an hour. Assuming everything equal the bitrate is ~5Mbps. Here's hoping we get some solid stats soon.
True, but isn't that widescreen 480? Not to mention that it sounds like the text would barely be readable on sdtv.
No, I have full screen 480i and I can change the menu to 16:9 enhanced. Get some bars on top and bottom just like you do when widescreen comes on regular TV but that does not bother me. Some widescreen DVDs are the same.
Text is small but if I want to read better, I just click on the item and it comes up larger along with options to preview, buy or rent etc. Not as good as widescreen TV but plenty fine until I can cut loose the funds for an upgrade.

The idea of having the movie in 1080p is a joke. It wouldn't matter if it was 1080p, because with high compression you are better off having 720p in higher bitrate.
Someday we'll get 3mbs playback from iTunes, which means that only 2ghz intel dual core, will make the cut, and you'll probably have Comcast, and ISPs suing Apple for your account that gets terminated from using 3/mbs for extended periods.

Stop spreadin FUD! Standard Definition iTunes movies are at or above 1.5Mbps. To think that HD movies will cut that in half is asinine.

DVD supports up to 10Mbps. I've seen a Blu-Ray or two that gets as low as 10Mbps at times, but it varies a lot, depending on the encoding and the footage. In practice, I think Blu-Ray movies rarely exceed 30MBps for video. Standard iTunes video is at or above 1.5MBps. I don't know if anyone has any information on iTunes HD, but I gather it's probably 3.0MBps or so. As for 1080p, I think it does need to be 8Mbps to be good.

HD-DVD has a maximum of 36.5Mbps, Blu-ray has a maximum of 48Mbps.
From my very rough estimate based on the downlaod speed it looks to be about 3x faster than my SD iTunes rentals. That means about 4.5—5Mbps.
I'm liking the changes in Take-2. Ratatouille in HD looks very nice, but the 5.1 indicator did not come on my receiver during playback. Are people getting 5.1 out of the HD rentals?
Unfortunately, music videos in a playlist will still not play back one after the other.
On the whole, a nice update that needs to be refined a bit more in the 2.1 release (assuming of course, that Apple is finally going to take this device seriously and start kicking out updates).

Maybe you have to enable 5.1 output first? Have you had a look in "Settings"?
I have a Samsung DLP TV with only 1 HDMI port. I was going to buy a switcher to add an Apple TV unit, but I've read in multiple posts that there is a bug in the original Apple TV sw that keeps it from working on an HDMI switch. (Before you respond that it must the the Samsung, be assured that a lot of folks have tested this and attributed it to Apple, not the switch manufacturers.) I'd really like any info from someone who is using an HDMI switch with the new sw to see if this issue has been addressed.
Thanks!
The picture AI used above in it's press release shows the atv sitting on a switcher, so it must work.
I've had my AppleTV hooked up to an HDMI switch since the day it was released and it works fine. Worked perfectly with the old and new software. I haven't heard of anyone having problems with an HDMI switch and an AppleTV... I use the Monoprice 3x1 Powered HDMI switch.
I just got their 4:1 HDMI switcher and the thing works like a charm. Not as pretty as the XtremeMac switcher (that looks identical to, and sits under, the ATV), but no one keeps those in stock.
Monoprice, btw, is probably the best on-line dealer I've ever dealt with, and their prices are outstanding.

Dobly Digital out is enabled. During the initial startup video, the 5.1 indicator came on and it sounded awesome. I hope the Handbrake guys can figure out how to get 5.1 into ripped movies so that I can just do it myself.
Edit:
So the visualhub guys have posted a video (scroll down a few posts) that does output 5.1 doblydigital on unhacked AppleTVs. It worked like a charm on mine. They are supposedly going to release a new version tomorrow (Wednesday the 13th). The VisualHub guys seem to indicate that file format will be limited to the .mov format for now.

Thanks for the info. How readable is the text?

See the edit on previous post. By the way, I have a 32-inch screen.

I can't believe an AppleTV HD 2 hour film is going to be 2GB. A 2-hour standard definition rental comes in at 1.5 GB.
Blu-ray = 14-50mbs
iTunes HD Movie = 700-900k per sec

BTW, this new ATV software update is fabulous! The device has suddenly become lavishly useful.
Definitely more useful, but the column and rows root interface isn't as slick looking as Take 1. The new intro is really slick, too.
Unfortunately, music videos in a playlist will still not play back one after the other.

I'm so glad you can spell. Sorry that you can't add anything interesting to the thread.
But we all welcome your spell check skills.
I thought it was pretty funny. But then, I'm a languageofile. No, wait...
