What's a good [FREE] program to test DVD burns?

[i am x]

I see that there is a program called "KProbe" that gives detailed tests of DVD's after they are burned. It tells the writing speed, errors, writing drop rates, etc. BUT.....according to the directions, it says that it ONLY works with a drive called "Lite On", or something like that. Well, my question is, is there a program out that that works with ANY drive that will tell the same info about discs that have been burned? Preferably a FREE program. Any info would be appreciated.
