I need a program to compare a master dvd to a copy. any recommendations?
I work at a church that produces and copies dvd’s of our services. We are having problems with a dvd’s from a particular duplicator and i wanted to see if the duplicator was causing the errors or if it was the master recorder.
Can anyone recommend a program (windows preferred) that can do a bitwise comparison on these 2 dvd’s?

Haven’t seen one. But if you’re having trouble with a duplicator- change. They are literally a dime a dozen these days.

I’m trying to diagnose whether my master dvd recorder is causing problems or if it’s one of our four 10-bay dvd recorders. They are set to automatically detect and set the duplication speed. Is there a correlation between the duplication speed and the number of errors on a disk? I have always assumed that the faster the duplication the more possible errors.
Also, I’m wondering how the dvd master encoding speed (sp/ep) affects the duplicates. is there a correlation between the encoding speed and the duplication speed?
my assumptions have been that a slower recording speed (with less compression) on the master will play better on a duplicate, even with possible duplication errors. and that the slower the duplication speed (12x or 8x) will reduce copy errors.
does the logic hold in this case?

Yep- in general the faster the record speed the higher the potential for errors. But if you use verification this shouldn’t be a major issue;
