My System: Toshiba Sattelite P25-S520 Windows XP SP2 DVR-K12D +/- R/RW I used to use DVD decrypter, DVD2One, and finally record Now Max to burn. This worked great. Around the time I got service pack 2, I this method stopped working. I have since tried compression with DVD2One and DVD Shrink, and burning with DVD Decrypter, record now max, and Nero. I tried using an image instead of files to no avail. Now every time I write a disc I get a Disc Write error during burning. I tried to upgrade firmware, it seems Pioneer doesn't even support my drive anymore. I tried checking the Toshiba site for updates, but there was nothing. I think this has something to do with Service Pack 2 but I'm not sure. I've probably wasted 30 DVD's trying to fix this....any ideas??????
