Hello, I have read in many of your fourms, to find a solution first. I found one simular, and tried what they tried and it did'nt work. Also I hope I'm posting in the right forum. If not I'm very sorry. I'm new.I have windows xp spk2 My dma is on 320 mb of ram I burn with nero ver.6 I have a 19gb hard drive(came with computer)and a 70gb drive.I have a I/o magic dvd writer Im using philips dvd+r. (witch I know is not the best but worked great before this happend). I tried to burn a dvd a few days ago and got this message Could not perform start of disc at once. burn process failed.I have checked for worms/spyware etc. I checked the dma/aspi. every thing was working fine aday before when I burned. Now when I add the files to burn with nero it has a music symbol by the video_ts.bu part.I would greatly appreciate your help. One more thing I also uninstall/ reinstalled the dvd writer to.
