in addition to what Halc suggested:
Mutliple media types need to be considered. I think for the moment we can ignore re-writable media, since it will probably bring with it a "whole new can of worms" and we have enough on our plates to consider as it is!
Multiple units of the same drive model... I know this sounds expensive and overkill, but it is of the utmost important to those of us that like testing our media to know which drives have consistant results between units of the same drive model, and which do not. We have already seen lots of variation from LiteON DVD burners... but I am curious about the BenQ, NuTech, and Plextor DVD burners, and also the new LiteOn 167T DVD-ROM which faired very well previously.
of course mutliple testing speeds must also be used in order to find where each drive performs their best, and also where they become as equivilant as possible to the CATS Analyzer.
In the end, a simple play test on a fairly picky DVD player would be nice too, since all the CATS scans in the world are pointless if in the end the DVDR won't play in a regular DVD player! So I for one would like to see where according to the CATS device, do problems start occuring in real world enviroments?
Yeah, I know it's a crazy amount of work! But I think if Emperor and crew can pull it off, it could quite possibly become like the rosetta stone for DVDR testing! Good luck guys!
