CloneDVD2 help

I am backing up a movie that is on 2 discs. I have a Lite-on LDW-411 (FSOJ) ,win2k, CloneDVD2 2.0.5.3 and AnyDVD. While reading to my hard drive, on disc 1, I keep getting the message “missing title VOB file(s) named VTS_01_*.VOB” at the 99% completion point. Kprobe revealed some write errors, but it plays fine in my standalone DVD and the LDW-411.

Any ideas?
Is there a way to force reading at a slower rate?

TIA.

Disc 2 of the 2-disc set stops at 5% of reading with the following error:

“Processing stopped: NavigationPack 6 0 62 158 VOBU 4 0 62 Clone 6 TCE”

Can anyone help?
