Multiple dvd recording in vista



I have windows Vista and quad core q6600 and 500gb sata HDD and 2 pioneer 216d sata drives with the same firmware…my problem is a lot of underun on one drive when doing dual writing ISO images…i never had this problem with XP on a old 3500 Athlon it used to write at 16X no problem with two liteon drives.

would a clean install of Vista be a good idea . as i have no idea what is causing the buffer underrun ?

thanks alot


What program are you doing this with?
