Just wanted to add myself to the list - and add a new twist to the mix. I'm in the US (VA), and have about 60 HD-DVDs. Last week I started on the effort of backing them up using my GGW-H20L/GGC-H20L drives, and noticed that four of them - all Warner, were completely unreadable.
For me, it was:
Blade Runner Collection Disc 5
A couple of them DID have some visible marking towards the edge of the disc, like an uneven brown ring when held to the light.
So, here's the twist. A couple of weeks before I noticed this with the HD-DVDs, I posted this thread:http://www.avsforum.com/avs-vb/newre...eply&t=1340990
This was about an earlier problem I was having (and still am having) with Warner DVD-Audio discs displaying almost the EXACT SAME behavior.
I know HD-DVD is not DVD-Audio, but I do know one of the sales points of HD-DVD to industry is that they could use conventional DVD production lines..
I have dozens of discs from other companies, and the ONLY problem I've had is with Warner.
I also don't think chapter-skipping is a good test. Some of these errors seem relatively small (but cause the player to freeze up). My 100% reliable test has been trying to make .ISO files with my PC drives.
I have not yet tried these on my XBox 360 USB HD-DVD drive, but I do have a couple of the Toshiba slim factor HD-DVD reader/writer drives coming next week - so I will try on those as well.
Perhaps some machines can read these discs? My HD-A30 and HD-A3 cannot.
