Nero can be made to work with dual layer burns, but it can also be confusing, depending on how you ripped it, and what software you were using when you ripped.
If you are just trying to do a one-to-one complete backup of a dual-layer DVD to a dual-layer blank, and you want an identical exact copy, by far the safest and easiest method is as follows:
-Use good media (Verbatim, for dual layer, is the winner in this regard);
-Use DVDDecrypter. First, use DVDDecrypter to rip. Go to the Mode menu, and select "ISO Read R." Rip the entire contents to your hard drive in ISO mode, and note the location where it is being ripped.
-Use DVDDecrypter to burn. Go back to that Mode menu, and this time select "ISO Write W." Now, browse and navigate to the folder where you stored the rip, and choose the file with the ".MDS" extension.
-Done.
Your quality will be every bit as good as the original was.
The method above should work for almost every DVD currently in existance, although this is bound to change when Sony / Columbia begins to release newer variations on their Sony ArCCos copy protection. DVDDecrypter will handle pretty much every one that is out there now, but Sony keeps changing the scheme, and DVDecrypter will no longer be updated to handle the "next" change.
And, regarding your original post that started this thread I would mildly disagree with one of the responses above, only in that it might have been a bit incomplete. Yes, sometimes a "choppy picture" is due to lousy media, or a poor quality burn, as one answer suggests. But, sometimes, it is also due to too much compression. The term "choppy" is a little bit vague, here, and it would help to know exactly what you see when this "choppiness" occurs. Would you describe it as "pixellization," where you can visibly see the individual pixels which make up a frame of video, and those pixels seem to be breaking up? Or, would you describe it as a "frame jump," where the picture seems to be "jumping" from one frame to another? Or, is it a stuttering or lockup problem?
The cheap media problems occur most often at the very ends of a burn (which may or may not be the end of a movie, due to all of the extras, etc.) Sometimes, in those cases, yes, it is cheap media, where the dye used in manufacturing was substandard, or it was not properly sealed at the outer edge of the disc, and is actually "running" at the very end.
If the choppiness is pixellization, it is more likely to be too much compression. If it occurs at randome spots throughout a disc, this is another clue that it might be too much compression.
