For copying CDs and creating data CDs, I use Easy CD Creator 3.5c (I got it new several years ago, but I think it's freeware now) and NTI CD-Maker 2000 version 4.2.66 which I got with my CD-RW. I have never had problems with either burning data CDs, although I would not recommend NTI to burn audio CDs (it puts skips and ghost echos into songs).
For burning audio CDs, I use MusicMatch Jukebox 6.0 which is a very good program and has an easy to use intuitive interface. I also got it free with my CD-RW, but I had to pay for the upgrade that enables you to burn at full speed; the demo only burns at 2x.
If you go to
C|NET they have some freeware demos that you can download to take for test-runs. I recommend against Media Jukebox; it's interface is clumsy and awkward to navigate, although it is a very functional program.
As for burning DVDs onto CDs; you really can't do it from a practical standpoint. You can copy the files from a DVD to a CD, but the storage capacity of a DVD is so much greater than a CD (4.7 GB as opposed to 700 MB) that the process is cumbersome and generally a waste of your time and media. Both use
basically the same technology. However, when the CD standard was established over 20 years ago, the lasers they used weren't as precise as they are today. Consequently, they couldn't read as much data on a disk as a DVD can.
Think of it this way: If you took an vinyl album and cut the grooves in the record so they are one-eighth the size they are now, you would need a new needle to listen to the album, right? That's the difference between DVD and CD; the DVD storage standards are that much more exact. That's also why drives configured for the CD standard cannot read DVDs; the lasers aren't meant to read DVDs.
What you can do is this: If you know which files you want from a DVD, you can copy those files to a CD-RW. However, you will need eight or so CDs to store the same amount of data. If you are copying a commercial DVD (which is illegal and the discussion of which is against the
GameBanshee Forum Rules, specifically rule #2), you will run into problems because the root directory will be off and will not know where to go when you go to change scenes or look for the special features. However, since I will assume that you are talking about copying DVDs that your brother made while on vacation in Hawaii at the Pro Bowl, I will recommend that you just buy a DVD-RW for $500 or get your brother to burn you two.
