Is DVD2One more "sensitive" than Instant Copy?

[Wolfmancatsup]

Dear all - a question - is DVD2One a little too sensitive to possible "squiggles" in ripped VOBs? I ask this as I have a problem.
I bought DVD2One a few days ago as it does EXACTLY what I need in backing up my films. A straight, no-nonsense, VERY fast backup of the movie - couldn't care less about the extras, as I have the originals if I want to watch those (and I don't tend to watch those more than once anyhow).
I ripped my copy of "Ocean's Eleven", and even though DVD Decryptor says "no errors", I get blocking occasionally throughout the backup. I tried transcoding again and get the same problems in the same places.
I then cleaned the original and ripped again - same problem but in different places, although when I then transcode again the problem occurs in the same new places (if that makes sense).
I tried Smartripper - same thing - my cousin popped over tonight with Instant Copy, and that produces a perfect copy (ie one with no blocking in the places I get blocking with DVD2One) - oh, and boy am I getting sick of watching the film!
Thing is, why does Instant Copy produce a "clean" backup whereas DVD2One doesn't - is there something in the VOBs it hates? Does Instant Copy suffer faults more gladly than DVD2One? Need some help here as I don't want to go out and buy Instant Copy (yes I know it was on my machine earlier but it ain't now - I'm not like that) as DVD2One is the program I want.
I've put this query to the forum on DVD2One and DVDRHelp to see if one of you nice folk can shed some light on this.

Ta,

Wc.

Instantcopy superior....DVD2One inferior.

It's just the encoding engine of the program DVD2DVD-R is the best out of them all to fit on one DVD-R. DVD2ONE can make better copies of some movie like the Matrix where DVD have a ton of extra and I mean a ton of extra's fitting every thing on a 4.7gig DVD Im not say DVD2one is better I'm saying taking a 9gig making it fit on a 4.7 you have to know what to use so I most case use instant Copy 7 if you like it better and for DVD that are real funky use DVD2ONE
