First thing, what type of DVD does your drive support? I have a friend who was unaware that his drive was a COMBO drive, which reads and writes CD, but only READS a DVD. He was unaware that he did not have the ability to burn a DVD! OK, so check the docs for what the drive can DO and be sure you even HAVE a burner. And if you DO have a burner, the second thing, what type of DVD media it supports. There are 4 types, DVD-R, DVD+R, DVD-RW, and DVD+RW. +R and -R disks are write once, read many, a WORM disk is what it USED to be called, +RW and -RW are rewritable media. Not all drives support all 4 types of media. If your drive only supports -R and -RW, then the +R disk you have will never be recognized as valid writable media.I only use rewritable media until I am sure I have something I want to keep forever. I master the disk on RW media and then simply copy to +R or -R media. My DVD burner supports ALL 4 kinds of DVD media. However, my DVD recorder only supports -R and -RW types, so that is what I use for everything. AND one other thing... drive support speed. MANY DVD burners do NOT support 16x media without an upgrade to the firmware unless it is brand new, maybe less than a year or two old since manufacture. For a firmware upgrade, you will have to contact the manufacturer. Most manufacturers have firmware upgrades available to support 16x media if your drive does not already do so. You have to run a program you get from them to perform the upgrade. I have 2 DVD burners. One would not support the 16x media but would handle 8x and slower perfectly well, while the other DID handle the 16x media. I was able to get a firmware upgrade program, however I have NOT installed it yet. Once you know your drive supports the media you are trying to use, music files are data files as far as your hard disk is concerned, and the same applies to the DVD as well, music files go onto a data disk. With video, you have other choices. The burner software you have determines what DVD types you can make. I use Nero Burning which came with both of my DVD drives. Other burner software is available from MANY sources, but I've not had the need for anything more than the Nero software which came with the drives. You can try doing a keyword search at http://www.tucows.com
and see what falls out. Both sites have a wealth of free and shareware programs available. Something like "DVD burning software" or some such keywords should turn up something you can try. Like I said, (and I do NOT mean to insult your intelligence) it is a common sense kind of thing and should be obvious, but are you sure you have a burner even? And if so, what media does it support?
