How come this movie is 'only' 12 GB and not 20+ as other HD-DVD rips?

just guessing...but maybe it is a shorter movie. Also, all the extras may have been removed. This is just a guess though.

From what i read here on the web (http://www.bigpicturebigsound.com/kiss-kiss-bang-bang-hd-dvd-803.shtml) it's smaller because it's a Combo-Disc with HD-DVD on one side, and a standard DVD on the other side.

This seems to reduce the HD-DVD Storage capacity to 15GB (from 30GB).

But according to the reviewer (see link) you should be able to live with that just fine:
"As with earlier Warner releases on HD-DVD, the picture quality of the 1080p widescreen HD transfer is top-notch, with excellent detail, nice color resolution and excellent rendition of shadows and darkly lit scenes. "

HD-DVD rip? Does that mean that HD-DVD encryption is cracked for real?

... and how do I view this format? VideoLAN?

PowerDVD

The first HD-DVD and Blu Ray disks were only single layer. Thats why its "only" 12 gigs.

If you use a digital connection from the PC to the screen, it might not work. For mye Chronicles of Riddick did not play on a DVI conneciton, but on VGA connection it did just fine.

is there a way to burn this to work on a normal dvd?

what software should i use to play this?

I have powerdvd 7.2 Blu-ray edition... plays nothing... not new to dvdr rips but am to hd-dvdr rips....help!
