LotR: RotK EE Problems

[]|[Mar']['in]|[]

Well I've got Lord of the rings: Return of the King extended edition and want to back up all 4 dvds.

I Copied the 2 appendix disks and burned them just fine no problems. However I'm having a hell of a time with the two "Movie" disks.

I've tried using DVDXCopy, Clone DVD + AnyDVD, and DVD Shrink.

The same thing seems to happen with each. Everything will go smoothly, it will ask for a blank dvd, I stick it in, and a few seconds later it errors out.

I havn't had any problems with any of the other movies I've backed up recently.

Any ideas? I don't remember the "error code" if there was one. I guess if I have to find out I can. It'll be another 2 hours though ....

Anyways, any help appreciated.
