Dvd -R DL discs.../Ps2 games/DVD Movie back ups...?

[sunny]

Hi....

There seems to be conflicting reports for Dvd -R DL discs.

Some people say say they work perfectly...for Ps2 games as well as dvd movie back-ups.

Others say that these discs do not work for Movies.../the layer breaks are not correct...?

Can someone please solve this mystery....?

Thanks.

DVD-R DLs are only partially compatible with DVD-Video. The first layer must be filled completely with data, unlike on DVD-ROM or DVD+R DL. This means that the original layer break is not at the right position. Therefore, you cannot do a 1:1 copy.
But if you use a program, like PgcEdit, to specify another layer break position, and you rebuild a new image, it is theorically possible to burn correctly your DVD-Video files on a -R. You can do that automatically with PgcEdit (which uses MKISOFS to build the ISO, and DVD Decrypter to burn it.)

Of course, the +R solution is largely superior, but you still need a good program to specify the layer break position and patch the IFOs accordingly, unless you burn directly the original image.

It is well known that Nero, for example, is not able to burn DVD-Video files correctly on a -R DL, but it has problems with the +Rs also.

I don't know for Ps2 games.

Thanks for the info...at the moment I'm using +R DL with dvd decrypter..and am getting perfect 1:1 copies.
If the layer break issue is resolved..would a stand alone player read the -r dl as a dvd -r disc...?

It seems Pioneers's latest dvd recorders (for t.v) will only support -r dl...?

Cheers.

If the layer break issue is resolved..would a stand alone player read the -r dl as a dvd -r disc...?I think so, since the -R technology doesn't support booktype settings.
