I have Sony DRU120C 16x DVD±RW Burner.

I have 3-4 sets of DVD-Rs of different companies that it used to burn at their normal speeds of 8x and 16x.

After burning few 8.5GB dual layer DVD+Rs using Nero, the burner now burns all the DVD-Rs at 1x speed. I have 2 DVD burning softwares on my machine: Nero and Sonic RecordNow. Tried both the burning softwares on all different type of DVD-Rs; reinstalling Nero; same problem.

Any help would be appreciated.

Thanks for the help and the link. I could burn my DVD-R in under 8 mins after 4 months. Here is what I did:

Run REGEDIT. Go to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}
It has subkeys like 0000, 0001, 0002, etc. Normally 0001 is the primary IDE channel, 0002 the secondary, but other numbers can occur under certain circumstances. You have to go through these subkeys and check the DriverDesc value until you find the proper IDE channel.
Delete MasterIdDataChecksum or SlaveIdDataChecksum, depending on whether the device in question is attached as master or slave, but it can't actually hurt to delete both. Reboot. The drive DMA capabilities will be redetected.
