Burning A DVD

I'm not sure...whatever came loaded when I purchased the computer. How can I find out?

I've been there...my computer is set to live file system format and I've set the computer to close the disc manually. Here's the problem. I've copied 125 photos to a dvd+rw with 4.7 gb avalable space. According to the properties of those photos, they take up 432 mb. I've tried to add 136 more photos (properties tell me that the photos are 454 mb) to the same dvd. (I have not ejected the dvd.) Here's the message that I get..."This dvd-rom drive is read-only. You can copy files to this writable dvd but you must insert it in a writable drive." This is the same drive that I used to copy the first 125 photos. Help!!!

Hi...

I've ejected the dvd and reinserted it...I've even shut down completely and rebooted. No change. Now I'm merging the two files into one and trying to copy to another dvd...hopefully all will be transferred. Perhaps this is just one of those "quirks" Vista. If you have any other possible solutions I'd love to hear from you. Thanks for your help up to now.

Hi Sharpman...

Thanks so much for your help. It's nice to know that there are knowledgeable people out there willing to spend time with those of us who are technologically (is that a word?) challenged. Have a great day!!!
