Copy a Copy of DVD?

Question: I am beating cheeks to get some videos wrapped up by Xmas.. My edit system is pretty sweet & i have been doing all editing & DVD authoring/burning on it.

Still have my old Win98 System with a pioneer 106D on it.

The plan is to transfer some DVD files over to old system & burn copies on that while i edit on my "good" system.

Should i just copy the VOB files from a DVD i already created and paste it to my old system hard drive - then burn from there...

OR... should i make a copy of the files to DVD using the DVD-DATA - udf format... (rather than DVD-Video Format) Then use that Disc to cut n paste files to my old system?

Thinking the Data Format .. on a .. well "Data" dvd has better error correction than it would on say a "DVD Video" disc.

Or is it the same?

Thanks in advance!

Use this open-source app.

1st - It appears the website owners removed that app.

2nd though.... this is just a copy of one of my DVDs.. a wedding video.. there is no CSS or any other copy protection...

My concern is data interigity between on the disc itself.

In nero - say you use a 'DVD Data' layout as opposed to the 'DVD Video' format.. is error correction different between the two??

Just do a disc to disc copy using nero and select the amount of copies you want to make from the one. Since there is no more recompression, there will be no loss.

I would just take the Video_TS folder copy and paste it to the computer and then reference that in nero to fill Nero's Video_TS folder. You won't lose anything as nothing is being recompressed or changed...just copied.

Maybe I'm just repeating what others are saying here:

Sure, you can take your "master" DVD over to the other system and just copy the entire VIDEO_TS folder to your hard drive, then use a burning program to make the DVD from that folder.

I guess in theory there might be a greater chance of errors, since you're burning from a DVD copy rather than from the original files, but unless the DVD is really crummy then error correction routines should fill in any disk errors that inevitably occur.

Note: My understanding is that this is NOT the case with making a copy of a copy of a CD. The error-correction algorithm there is nowhere near as powerful.
