I'm going to buy my first hd-dvd when Blade Runner comes out in december. Will I be able to watch it on my CRT monitor? My computer is fast enough, but I don't know if the DRM on the disc will stop me from playing it.

No reason why not. You need HDCP if your using DVI, but if your just using VGA it'll work fine.

The reason I'm asking is that I have heard that some programs downsample the video to non HD-quality. Also I tried playing a ripped blu-ray disc and it said that I didn't have the necessary hardware although I could play the video files without a problem if I opened them directly in powerdvd.

They downsample on DVI connections without HDCP. Bizarrely they don't downsample over VGA. AnyDVD HD gets around this anyway, as do any of the AACS-defeating backup apps.

That's not so bizarre: DVI gives digital output, so you could capture the uncompressed bitstream in a lossless way and then burn it on a disc or do whatever you want with the video. In order to prevent you from doing that, they only allow encrypted digital output (HDCP) over DVI - or downsampled resolution in case HDCP not supported. So if you capture the digital output, which is only possible without HDCP encryption, then you don't get the full resolution of the original. Capturing from VGA is way less interesting than capturing form DVI, because it's an analog signal. You can't capture that in a lossless way anyway. You will always have a huge loss in quality compared to the original due to the unavoidable Digital -> Analog -> Digital conversion...

Would the signal really degrade that much if you had a DAC that connected directly to the vga out of your video card?

I think so. It's well-known that LCD Screens benefit a lot from using DVI instead of VGA, especially at higher resolutions...

Will I be able to watch it on my CRT monitor? My computer is fast enoughAre you certain? My setup includes a 3.2GHz P4 w/X1950PRO video card, the hp HD100 HD-DVD drive, and PowerDVD Ultra, and a 21" Dell 1600x1200 monitor. Can't play HD-DVD without stutters, though if I overclock the CPU I can get "almost perfect".

This new HD-DVD technology is something else, what with its sometimes >30Mbps bitrates... :eek:

Shows how much of a jump the Core2's are, because even the low end ones can play HD-DVD.

I got a Intel Quad CPU at 3 Ghz so it is not a problem.

Methinks you are good, yes! I also agree w/Shakey_Jake33--I have another PC w/a Core2 and it's noticeably faster. Waiting for the day when my P4 craps-out and then... is there a faster CPU than yours kallekill?

Yes, I believe the new Penryn Core 2 chips come out in November and they have a Quad-Core at 3.3GHz.

My stock speed is actuallty 2.4 Ghz, but I am running it a 3 Ghz without even touching the CPU voltage. I haven't tried higher, because the airflow in my computer isn't optimal right now, but i think I could get the CPU up to 3.5 Ghz without a problem. The 2.4 Ghz Quads are really cheap. They cost around 266 $ and they are really, really fast. They produce alot of heat though so you got to have good airflow.

Thanks, guys--maybe Santa will be extra good to me this year... :)

kallekill you've given me another idea--maybe if I overclock the heck out of my P4 I will kill it. Then the wife will have to concur that I need a new mobo/cpu/ram!!!

About the digital->analogue->digital conversion. The amount of quality lost here is tremendous.

The first digital->analogue conversion is done by your graphics card, which probably cost in the region of £300 at most. In broadcast, they frequently use standalone digital-> analogue converters that cost £1000+, so how good do you think the quality of the conversion done in your pc is compared to that?

HDDVD on my CRT monitor looks really good. I haven't got a LCD monitor that support resolutions of 1920*1080 so I can't really compare though. I think the biggest quality loss comes from the analogue->digital conversion though.

When do the use digital->analogue conversion in broadcast nowadays when everything is broadcasted digitally?

You'd be surprised at some of the crazy things they actually do in broadcast.

Also A->D converters are a similar price to D->A, so either way a home system will loose some quality somewhere if there's an analogue component in the signal path.
