Very Small Ring On The Media!
« on: December 05, 2005, 10:38:00 AM »
Hi guys and gals,

Some days ago I found a very very thin ring on the undersite of my game DVD (PGR3). It's located at the inner part of the dvd, it's very very thin so you have to look for it very sharp!
Maybe this is a reason why the DVD laser can't read the data part. It reads the video part and then can't "jump" over the thin ring to read the data part.
What you think? I could take some pictures to prove it.

Regards,
Explizit

Ok I took some photos of my DVD. It was very diffecult to take photos on which you can see the thin ring. Download them and view (and zoom) them with a tool like photoshop or some similar one. Don't use the windows own viewer, it "blows" up the pixels too much so you can't see the ring.

Maybe the video part is not located before the ring, it could be the ring itself because video part is around 7MB big only.

If you have trouble to open them by clicking the link, try "Save to..."

Try "Save As" now, here it works. If it doesn't work for you, I'll upload it to another website.

That hoster isn't very reliable too. Damn, any suggestions for a better one which allows photos bigger than 2,5MB because I can't compress it more. Then you can't see the thin ring.
When I know a better one, I'll upload them again.

either you have scratched the disc, OR

the media is copy-protected with "LockBlock" or "Ring PROTECH". both of which use visible circles on the surface of the CD/DVD to prevent copying.


Well that sounds very reasonable...

I have not scratched them. I bought the game, opened the box and looked around the underside of the DVD. It's a ring used on old pc games to protect them to be copied (laserlok etc.)

If this is a break in the data on the CD, wouldn't it be possible to do a raw dump on it and fill the blank, with some random dummy data?

Maybe then, we could start getting somewhere with the xbox360 file formats.

According 2 me , it's a kind of composite format of DVD track and 360 track, internal track it's a normal dvd format, after: -leadout dvd- leadin 360 FS - 360 FS... right?
