jabroney12: As I mentioned at the beginning of my previous message, I never tried Verbatim brand media. I tried Memorex (Mitsubishi Chemical) and CompUSA (Optodisk). I saw many positive comments on Ritek and Fuji brands, but haven't tried them yet.
For testing I have the following players: xBox, Samsung DVD C631P 5-disk DVD changer, EPO 12X DVD-ROM drives in my computers, and, of course, the Optorite DD0203. Again, I did not have luck with any type or brand of media that would play on all my players. I guess I need to do some more research until I find a perfect match, but the research becomes pretty expensive when you have to buy spindles of different media for testing (or expensive single ones).
You can check the compatibility of types of DVD media (+R/RW, -R/RW) with DVD players on
http://www.dvdrhelp.com/dvdplayers.php, but I don't think that site provides accurate info. For example the site states that my Samsung player is capable of playing both -R and +R, but user's manual mentions -R/RW only (although Memorex +R works, and CompUSA +R doesn't). I wish that site would also provide brand of media that would work with listed players.
