when i run nero (126.96.36.199) and try to write an iso onto a blank dvd, the "used read buffer" goes to 100% perfectly fine. however, the "buffer level" down next to my burner's name (PIONEER DVD-RW DVR-104) stays at 0%. after a minute and a half, nero fails attempting to write a lead-in. no coasters, as it doesn't write anything at all. after searching around on the net i have changed my burner back and forth between udma-2 and pio-4, settling now on pio-4 but still no luck. decrypter 188.8.131.52 and alcohol120 184.108.40.2065 have the same problem--no "device buffer" and fail on lead-in. I even reinstalled windows without windows update, without my via 4-in-1 drivers, and without forceaspi 1.7. all to no avail. here's all the different errors dvd decrypter has given me: no more track reservations allowed L-EC Uncorrectable Error invalid address for write no additional sense information today i just got done burning a couple iso's using my burner and the same nero in a friend's computer just fine. does anyone know why my drive seems to have no buffer on my computer? or what else could be wrong?
