Considering beefy PCs can do 1080p24 via WM9, it really shouldn't be too much to ask from BD.

I heard the WMV samples are really around 1400 pixels, not 1920.
 
Good idea Teasy. Find a comparable "tv-like" movie as well if you can. I wonder if there are available movies on the net that clearly illustrate the difference.

Does playing them back on your PC monitor though, skew the comparison (because it's not the same thing as watching a SD source on an SD monitor compared against watching an HD source on an HD monitor)?

Yeah there is that, but I'd really like to see it moving. I'm downloading a couple of movie samples from alt.binaries.hdtv, so I assume this is hi definition content (they're pretty big for samples so...). Hopefully they will give me a good idea of what HDTV looks like.

It will, just have in mind that most of that stuff is not using a very high bitrate, and some of the stuff has pretty bad transfers. The trailers from new movies are ussually the best quality along with live stuff like Award shows and Sport.
 
I downloaded a couple of samples. One was a sample of the movie The Ring at 1280x720 but unfortunately it looks for a codec download and then refuses to play when it can't find it. The other was a sample of Alien which looked for a codec and then, when it couldn't find it, played what looked like green screen or something.. very od. Both vids were DivX and I've got both the DivX and XviD codec.. Ah well I'll keep trying :)

EDIT: Ok I got one of them to play. Its a sample of Coyote Ugly at 1280x720 using the DivX Codex. It did look quite sharpe. But unfortunately I think the video sample rate wasn't quite high enough as I could just about see some artifacts when I looked very closely. Which would obviously ruin the effect of HD.

720p can be in anything from 24 to 60 hz so a 60hz 720p picture will look (looks) very smooth if the source is 720p 60hz, for example video. But a movie will not benefit. 1080i on the other hand can look really impressive the sheer number of details is just awesome.

Progressive film telecined into 1080i and automatically ITVCd can be impressive ... that is quite irrelevant to 1080i as a format. It would be better to just standardize on 1080p at 24 Hz for that kind of content, and not to confuse the issue.

True interlaced content (not to mention the bogus telecining methods people keep coming up with, people are still fieldblending for christ's sake) will cause another generation of poor format conversion and deinterlacing problems (especially with displays going progressive).
 
VC-1 and H.264 were both carefully designed to decode well on cheap DSP's with no FPU. There are already DSP's aimed at H.264 decoding (and encoding) and my vague understanding is that the cost isn't bad.
 
Well I finally found something worth looking at. A 1280x720p sample of some dinosuar show which apears to be recorded from ABC (it was in .TS format). 70MB for about 1 minute so pretty high quality. It does look pretty great, extremely crisp and clear!

Bluray Supports 1080p at 24 hz, it is part of the standard (check the .PDF i provided)

Nice to hear. BTW Im not argueing against blueray, Im argueing against the clusterfuck which is interlaced encoding of video in general and 1080i in particular.
 
I thought 1080i was the highest resolution they could sustain given the bitrate/bandwidth constraints for broadcast video.

With BR, they're talking about 36 Mbps to deliver 1080p. How much spectrum would they have had to allocate to deliver 36 Mbps instead of 19 Mbps?

The other thing is that the manufacturers who sat on the ATSC committee knew having to deliver only progressive sets would be prohibitively expensive.

Right now, 1080i is more common than 720p. Now 1080p displays are coming but only in the high-end, at least for now.
 
1080i is at 50/60 Hz (field-rate). 1080p at 24 Hz uses roughly same number of pixels but has far better coding efficiency ... so bitrate isnt a problem (or at least it is more of a problem for 1080i).
 
They're just too expensive for a late 2005 launch. I get the impression that MS is really tired of loosing so much money on the hardware. And that makes HD-DVD quite an outside possibility from my point of view.

Depends what kind of deal they are willing to give. If they're willing to cut low and drop the price over time nicely as costs decrease (something I don't believe they got with many parts in the Xbox), MS may decide it's worth it.

But depending on how early the launch, one side or another may decide the costs just aren't worth it to push for HD-DVD's inclusion. Unless one side hits COMPLETE desperation. ;)
 
But the risk with HD-DVD is that they may back the format which loses.

Right now, BR has most of the hardware manufacturers lined up. They also have some content lined up, like Sony's own Columbia, which will mean Spiderman 1, 2 and probably 3 by the time BR launches.

BR has greater storage capacity off the bat and has the prospects for more down the line. If will have greater recording capacity, which was one of the reasons VHS beat Beta.

However, it's assumed that Warner Bros. and Disney are leaning towards HD-DVD because Warner has patents and Disney has a deal with Microsoft. WB and Disney combined command over 40% of the DVD marketshare.

Disney was a latecomer to DVD. It tried to back DivX but eventually came to its senses. However, Disney won't have Pixar films to sell after one more film and Pixar sold a lot of DVDs for Disney.

It's a risk for both sides, unless the studios start to show their cards.
