Problems Making Dvd Movies

I am having problems making DVD movies with Nero 6 & Sony mod 710A. When I get to the step of converting mpg file to a DVD file or disk, program stops at any ware from 5 min. to 1h 10m. When it stops I must use ctl+alt+del or hold start button in to restart computer.

I am on 3rd DVD-RW DL drive with same problem. I also replaced power supply because it showed low 3.3 voltages of 3.104 with some voltage spikes too. I reloaded WIN SP2 2 times removed & reloaded Nero 6, 2 times, removed Studio 9. I have updated ASUS bios, Nero 6 , wnaspi.dll, Sony firmware, all to no avail I ran the Sony test and it passed. I tried to change mpg or avi files to a DVD movie file and save it to a file with same results. This makes me believe that it is a computer problem, not a the Sony DVD-RW-DL drive.

Any help would be greatly appreciate & cut down the cost of making coasters.
