Hey Vinnie,
My 708A burner burned everything I threw at it so far...
The best media to go with usually are Verbatim DataLifePlus (but pretty much the most expensive)... TDK's are also really good.
For DVD-R's I've heard that Ritek G04's have been really good (I ordered a few the other day - so I will be sure to let you know how they turn out).
There are tons more that I cannot think of off the top of my head... oh yeah - Memorex isn't bad either...
I am sure there will be a lot of brothers and sisters here that will give their top media choice as well...
What program(s) are you planning on using with your new burner? Sometimes people complain that the media they use is no good - where it actually is the program and its settings they used which wasn't the good choice.
Hope some of this help!
