Here's what happened and what's going on..........
Reformatted hard drive. Reloaded Vista. Reloaded Vista Service Packs 1 and 2 and all other available Vista updates.
Everything is working fine with ONE exeption. The DVD burner WILL do the following:
Reads files off DVD OK
Plays true DVD format disks OK
Plays other video files off DVD (like AVI, WMV, etc.) OK no trouble.
It WILL burn files to a regular CD (any files seem to work. Docs, video files, audio files are all burning to CD fine)
The ONLY thing it will NOT do now is burn a true DVD. I have tried using Windows DVD Maker (which had always worked just fine before) and tried other DVD burning software (Like Roxio) and both have the same problem. They both will let me add the video files and they both run ALL the way through the encoding and everything is looking good UNTIL it goes to burn the actual image to the DVD. It's at THIS point that it fails. The onle message I get is "Windows was unable to burn the DVD" It then suggests I try reformatting the disk or try the burn again. Same problem when using either Windows DVD Maker or Roxio.
Wierd, huh? I have searched this and other forums but nothing seems to help. I THINK I have all pertient drives and updates loaded but it sure ACTS like some driver that controls the actual burn of the image is missing or damaged or not working or something like that. I don't think it's a hardware issue as everything else including burning of regular CDs is working OK.
Any one have any ideas??? ALso tried slowing the burn speed down but same problem.
