I have installed a Pioneer 108 as an external drive through an enclosure that connects through USB. It seems to work fine, when i used DVD encrpter to rip it worked like a charm. However, every time I have tried to burn the dvd using NERO it has failed before it can even write the lead-in. Can someone please help me figure this out? My system is as follows: AMD AthlonXP 1600+ 512 DDR ram Western Digital 6gb harddrive Maxtor 30 Gb harddrive TDK velocd drive Toshiba DvD rom drive Pioneer DVR-108 (external) direct x 9c Nvidia Ti4400 video card Any help is greatly appreciated.
