I have a P4 2.53GHz with 768Mb, NEC ND1100A 4xDVD+R/RW drive. The comp was bought from Dell last Jan, and at the time was incapable of burning 4 speed with +R. With a Dell firmware update for the drive, the drive was able to burn at 4 speed. I am using DVD Decrypter (Ifo mode for main movie only) + Ifo edit + DVD shrink 3.14, or sometimes DVD shrink directly (I have found DVD shrink doesn't like taking the film straight from a DVD-R disc, or if it does then it is excruciatingly slow, whereas DVD decrypter has no problems ripping VTS/VOBs from a DVD-R). I am burning using Nero 18.104.22.168 (Nero 6 doesn't like my drive, and it doesn't place all the VTS's, IFO's & BUP's in order automatically for you. Half of all burns produced at 4 speed have glitches in when played back, although the comp says the burn was successful. I am using Datasafe 4x DVD+R (Ritek dye) as they're the best discs i have come across at the price. The burned discs are 100% at 2.4 speed burn. The burn buffers on display are keeping up whilst burninig So what i need to know is, is Nero shite at 4 speed, is it the discs at 4 speed, or does my DVD burner not like operating at 4 speed? Anyone got any disc reccommends? I can get the discs i am using for about 90p each when bought at a computer fair in quantities of 100. I have tried Aritas, and they're great, except some have solvent marks on the recordable side (about 2% of discs in a bundle are affected). The old datawrite 2.4x black and yellw discs are ok, the 4x frosted datawrite +R's are shite (about 60% failure at 2.4 or 4 speed). Thanks!
