I'm a bit new to this game. I've recently been suffering the same jumping problems myself. I've been using Datawrite Classic 4x DVD-R's (Yellow Label) in my NEC ND-1300A DVD writer & up until now I've had very few problems although friends who have tried my disks in their DVD players have suffered "jumpy bits" at the end of the disks.
Now I'm having all sorts of problems! The DVD writer will only write if the machine has been switched off for a goo few hours. Otherwise I get a "WriteDVD 9" error (using CloneDVD).
Even when the disk is written sucessfully its hit & miss whether or not I'll get a working disk or if it will end up jumping half way through!
I'm wasting disk after disk at the moment but I've only got about 4 left so I'm looking to get some good quality media for my next purchase.
Could anyone suggest any good quality products for the NEC ND-1300A?
(I've updated the firmware to 1.0B as suggested elswhere in the forums)
All suggestions welcome, as I say, I'm a bit new to this stuff & dont want to throw good money after bad on poor quality media. I'd much rather pay that little bit extra & get a product I can rely on.
