[ProAudio] DVD Dubbing Problem

[Jim Brown]

I'm in the process of dubbing music performance with world class players 
I recorded 20-25 years ago using a Canon XL1 writing to MiniDV. The 
audio is 16-bit 48 kHz, I recorded acoustic music with very good mics. 
The XL1 has pretty good glass, well above consumer grade.

I've successfully managed to write DVDs with FireWire between a semi-pro 
player and a decent consumer DVD recorder. Now that I have the DVDs, I'm 
looking for a method to make bit-for-bit copies of them. I have no 
rights management to deal with. I need 3-5 copies of each program. My 
goal is not add a generation of data compression, without the need to 
make a transfer from the master for for each copy.

I've found a review of a half-dozen or so Windows programs that seem to 
do it, but I don't trust the reviewer to know about data compression and 
generations.

Any advice? Places to look?

Thank, Jim Brown
