Actually, that's a writer, not a recorder. Moving you to DVD Writers. You might check if the drive has reverted to PIO mode as that may be one cause: To check DMA/PIO mode within Windows:

Control Panel>System>Hardware>Device Manager>IDE ATA/ATAPI controllers.

From there, right click on one of the channels and choose 'Properties>Advanced Settings'. All drives should be DMA mode. The 'Current Transfer Mode' for Hard drives is usually DMA 4-6 and DVD burners DMA 2-4, DVD ROMs usually DMA 2. If you see any in PIO mode, that can slow things down.

Changing them back may be easy or complicated. First see if you can change them in that window. If not, I usually uninstall the channel the drive is on and let the OS reinstall it. This will usually take a reboot. This will not damage any files on the computer.

If that doesn't help, get back to us.

Also, what program are you burning with? Most have buffer underrun settings to prevent this.

If you continue to have problems, I would replace the drive. Most media now is 8X - 16X and that burner is a little out of date for a lot of it.
