Go to Plextor's site and look for a firmware update for your burner device itself. Then go to Nero and see if there are any hardware/dvd device updates, not necessarily a Nero PROGRAM type update.
Once done, make sure that you have defragged the partition or harddrive that holds the movie file that you will be burning so that all pieces are then lined up properly together rather than making the harddrive bounce all over the place looking for each piece.
Reboot the computer after doing each of these things, then try burning again. I sometimes have to resort to slowing down the burn to 4X in order to prevent the underruns depending on the original movie and the codecs needed during the encoding process prior to the actual burn. Takes a little longer, but the errors stopped completely, and I've found I don't have to slow down the burn process very often anymore.
I have burnt 3 out of 4 dvds and this is what i experience:
During burnin, with Nero 6.6, the buffer levels keep emptying and filling. The light on the drive's panel will go from the "blinking" orange (burning in progress) to green (burning has stopped/paused) and vice versa.
This happens every couple of seconds, and writing at 8X on Fujifilm DVD-R will take as long as 25 mins sometimes. The one time this never happened (when burning never paused), burning at 8X took around 8 mins.
All 4 dvds that were burnt were full 4.7GB DVDs, and although i experienced this problem, the dvds could still be read after i tried them in 2 different DVD drives. Thank God for Buffer Underrun Prevention.
Is this normal behaviour.
I must mention that when burning the first 2 DVDs, i had about 2.5 gb (out of 54 gb) of space left. I freed up some space and burnt the other 2 DVDs with 11 gb of free space.
I tried restarting first, closing programs, disabled NAV and same problem. I have Lavasoft ad-aware, and pop-up blocker enabled.
What i think is that the burner is demanding more information than the hard drive is supplying. This is just what i think. But my computer isnt exactly that old-aged. I take care of it well. The only problem i have is that i keep my HD more than 75% filled and hence why i am trying to back up on DVDs now.
Im running XP home SP2, 2.4 GHz P4, 256 mb RAM.
Please help me correct this problem. Is the burner, the computer or the DVD media the problem?\
Thanks in advance.
