From 3 days I'm testing 708a and results are at least strange.
I can burn everything - however some cheapest media are rejected. But after burning some DVDs - I can't play them in standalone player. I have Apex1500 and Philips724 - both of them are rejecting +RW burned at 4x. DVDs burned at x2 have probs also - freezes, very slow start, unable to play after switching chapter. I used tested media for last tests - TDK and Verbatim, both recommended by Plextor.
I like the drive itself - very nice-looking, quite and fast, but I will have to throw it away, for now I lost maybe 10 dvds, none of them is playing without problems.
Firmware is 1.04, OS WinXP SP1, Nero supplied with drive, ASPI - latest. Video was created mostly using Edius, converted via hw encoder, then authored using Encore DVD or DVD Workshop 2.0.
BTW: Plextor support is "thinking" from 3 days, Im beggining to daubt in their famous support.
Any suggestions will be very appreciated, Im close to put this 708 after the window.
