I'm on my second PX-716A. My first one (TLA#0202, v1.05) stopped reading any recorded media, although it still recorded fine. I sent it back to Plextor and while aiting for the replacement I recorded a bunch of -Rs (Fuji branded ProdiscF01) with a NEC ND-6500A in my laptop. They all play well on my Sony DW-D22A and home DVD players.
The replacement (TLA#0304, v1.06) PX-716A cannot read any of these -R discs. The drive seems to burn and play discs it records fine, but just won't play these -R. What's up with that?
