System Info: WinXP SP1 Nero Ultra v6.0 DVD Shrink v3.0 Sony DRU-540A DVD Burner - supports +/-R; +/-RW Media used - Memorex, Sony and Maxell (all -r) These are the steps I use when backup a DVD: 1. Shrink to my HD from source to fit a DVD-5 (4.7G) 2. Use Nero Burning ROM to burn VIDEO_TS folder to blank media. Successfully burned DVD+R, +/-RW with the above media brands. However I can't burn using DVD-R. What's going on??? Can't understand it. I do not get errors. When I get to the 2nd step, my HD light is always lid - seems to be frozen. Checked WinXP Task Manager, it tells me Nero Not Responding and I can't even eject the DVD. Need to the a cold reboot. Exchanged my SONY DRU-540 with another new DRU-540. Same thing happened. Tried with different burner software such as CloneDVD and CopyToDVD. PC frozen getting to step 2. This annoys me!!! Please help. I don't like to call SONY, NERO or Microsoft. One tends to blame the other and you will get nowhere except wasting time. So I am hoping someone could provide some clues here. Thank you in advance!
