Somehow after FAILED attempts to burn .AVI (movie) files to a Memorex DVD+RW disk, my computer is treating the disk as if it is a DVD-R disk. 

I've been using CDburnerXP to try to erase the disk and it keeps telling me that the disk is not erasable, telling me that the current disk format is "DVD-R". 

Is there a way to change the disk format back to the way it was?  C'mmon, get another disk...and stop banging your head.Believe it or not, I'm not interested in saving money, so I couldn't care less if I am able to use the disk again..

The reason I asked is because I AM interested in learning how to change the bit settings..  The more you know  in computers, the more independent you are, IN MY OPINION.

I understand that the format of the disk can be changed but I was never successful at doing it before and was hoping to get some pointers on it...

For starters, what is a good program to use......
Learning is always good, but in this case, I think, the disk simply went haywire, and it's not good anymore. Not uncommon with optical media.heh, actually it was two disks that went haywire...I only mentioned one disk to keep it simple.........and a third disk is in question at the moment..

I believe the PROBLEM could actually lie in my drive..............It is suppose to be compatible with most optical media, but it fails to recognize CERTAIN brands of disks....For example: It will not recognize FUGI DVD+RWs, but it does recognize Memorex DVD+RWs.......Even the disks that it CAN recognize it has troube reading sometimes...Generally a "restart" is required at that point.

I flashed the firmware in it once a while back and the condition of the drive didn't change...I thought that maybe an updated version of the firmware WOULD change/help the way the drive reads the disk..............but condition is still the same..

The time I spent troubleshooting that optical drive tought me a LOT of stuff....I have no regrets about purchasing it, because of that........However, I ready to toss it out the door....I think I've squeazed enough lessons of out it...

You're correct. Some optical drives are picky.It seems that Windows 7 works better with my DVD Writer...

I was using Windows Vista when I could not get those DVD+RWs to work...

I just installed Windows 7 Beta, and CDBurner XP teats IS able to erase the disks...

It could be that there were corrupt files in Vista that were preventling the proper function, and that a general fresh installation helped the disks to work...

Nevertheless, the Drive seems to work better with Windows 7.Since Vista is first generation to DVD burning capabilities i would say yes this is a distinct possibility
