Getting BAD dVD burns using Duplicator

[sportboards]

I have a small business doing Sports Videography. Here is my typical process:
1. Film a lacrosse or soccer game or whatever using Sony Vx2000 camera and DV tape.
2. Import into Mac G5 using Imovie ( simple and basic)
3. After setting chapter marks, I move to IDVD.
4. Burn a master DVD-R using the G5
5. load master into DVD duplicator ACARD controller 1 to 3 duplicator. Uses Pioneer Drives, I think !

PROBLEM: Lately, I noticed a DVD ejected from drive 2 with a fail code that I did not write down. I had gotten word back from customers that some of my DVDs were skipping, freezing etc. The DVD from drive 2
- will play back OK using my Pioneer DVD510
- will not play in my Apple G4
- will not play in my Phillips DVD player
- will play Ok in my Apple G5
How can I be sure its a drive 2 problem ?
Is there a way I can test the quality of the DVD -R using sofware that runs on a mack??
It is kind of weird ! The store I bought the duplicator from ( which they build up themselves) told me to use a DVD lens cleaner. Make sense ??

Any advice here ? You think the ACARD controller could be bad ?

Maybe I had bad DVD-R’s ?? Probably not, I produce a good master suing the G5.
