Technically, this is not true. A CD burned with WAV files will be a
data CD and will generally only be readable by computer drives, not
standalone CD players. It is true that when you rip a CD to your hard
drive, you generally wind up with WAV files (unless you want
compressed MP3s), but that is because WAV is capable of the same kind
of quality as CDs -- 16 bit 44.1KHz.

These are really two different questions. In the first question,
you're asking what the equivalent computer file format is to WAV. I
think this would probably be uncompressed AVI. I believe (but I'm not
positive) that all the MPEG based formats use some kind of lossy compression.
When you burn a DVD, though, you're not just putting AVIs on a DVD,
just as you're not just putting WAVs on a CD. There's an authoring
process that creates the DVD in a way that a DVD player understands.
And just as you can use a CD burning program to create an regular
audio CD from MP3s instead of WAVs, you can use a DVD authoring
program to make a DVD from files other than AVI. But the quality of
your CD or DVD will be limited by the quality of your source files.
There's also a video CD (VCD) format, which is lower quality than
DVD, and most currently available DVD players will play those as well.
