716a TLA#0202 FW 1.04u
Mitsubishi Chemical US-RW 24x (Plextor)
The media used is already two years old and originally came with the Plextor 48/24/48a. The first scan was a burn done after a "quick" erase, the second scan shows the same burn done again, this time after doing a "full" erase.
Conclusion: Can the 716a burn CD-RW well? I do think so. As always it doesn't hurt to use good quality media.
Also it pays off to do a full erase now and then
Oh yeah, to answer your question: I think it is media dependent.
