@TeeCee: CD+G means CD-Graphic, a similar way to tweak a little an Audio CD to store small bitmaps on the same place where Title, Artists, ... are stored for CD-Text (subchannel, don't remember which).
Hum, Plextor is on fire these days, after the rocking Premium...
But according to the specs published on their european site, this DVD combo lacks all the nice features Premium has got (Q-Check, GigaRec, SecuRec). Strictly reading, writing CD-Text isn't mentioned as for PX504A (on the contrary, for the Premium, it is), so it is not supported ? Strange !
Hum 2 MB buffer: tss, you're right guys, this is weird !
DVD x1 is approx 1500 KB/s, x4 = 6 MB/s, x8 = 12 MB/s
and 2 MB buffer: hum do the math ! Underun occurs in approx 1/3 s for 4x and 1/6 s for 8x. 1/6s: is it possible this drive actually works ? We don't want a x8 drive which triggers the BP so much it "hits" x4 perfs !
We will see.
