Burning issues

[DEvok]

hello, im sure most of u are familiar with Nero, nero vision and maybe other burning tolols like dvd santa. recently iv been having probelms with my laptop when it came to burning dvd's files, after transcoding and after burn." AT EARLY STAGES IT WAS FINE" untill 6months after, now i cant seem to burn things correctly and what i mean is files sometimes burn to 80% and fails.. or maybe it burns 100% pops out states all good" i try to run the dvd.. fails...
another issues would be when after converting files to dvd after it burns its all done again. but the cd is BLANK! wasted " or burns a few movie files and works and lets say 3/5 files work, on the 4th episode it freezes, iv been using nero-nerovision 7" on my WINDOWS vista and it has been 100%!! fine. maybe my dvd burner is screwing up???? i dont get it, it reads CD's perfecly??? is buring a cd and runing a CD different?? i swiched to nero8 same problem and all other dvd applications screw up as well. i think ima goona take it in for a check, please dont advise me to use some other dvd burning tool, coz it wont work!
thanx for reading. cheers!

Reading and burning are different tasks. Buring a disc requires the laser to output a more intense beam that actually burns the dye in the disc. Reading a disc require far less power. So it may be that your drive's laser or control circuitry is beginning flake out. Eventually, it may even fail to read as the drive deteriorates and isn't able to put out adaquate power to run the laser in read mode.
