Ah, ok. How can I get .WAV files from my CDs? Is there a way to do this
using WMP, or do I need some special audio tools like Audition or some
such.

Wav files ARE actually on a CD.

No, they are not.

But over the years I'm finding it really hard to actually open up and
explore a CD to get these files.. I used to be able to just gointo the
windows file system and get this straight off the CD..

I don't know what you used to do, but the CD spec hasn't changed since they
were first introduced.

However, I'm sure at some point it looks like Microsoft has made this a
little more difficult at the record companies request most likely.

No, not likely, nor true.

Plus, they are at a different format of wav. They are set at 44.1K/16bit.
You'll want 48K/16bit.

This isn't a different "format" of wav, but a different sample frequency.
There's no reason not to use the audio at 44.1k.


Here's also a cheap way to do it. Download iTunes from Apple. Put in a
CD, and "rip it". But, before you do that, go to preferences on iTunes,
and change the preferences to either .aiff or .wav instead of .mp3. Make
sure to make it 48K/16bit. And, if you like, you can also change the
location to where everything is saved too, so you know where it is once
you rip it.




Hmm. I assumed it would perform better on my laptop rather than a DVD
player, but as I say, I'm new to this hobby so I appreciate your
insights. Apart from the issue of computer reliability and obvious
convenience, are there other factors favoring use of a DVD instead of
just playing the movie on my computer? Will the quality degrade when
moved to the DVD format?

Is your project starting out in HD? If your project is starting out in
SD, then going to a SD DVD will give you equal quality done with a higher
bit rate.

No, it will not. DVDs use video in mpeg2 format, which is a lossy
compression codec with a maximum date rate under 10 mbps. The video on the
OP's computer can be anything from uncompressed AVI to, most likely,
DV-codec-encoded AVI (he's using D-25 source material). The latter results
in a 25 mbps data rate, is not further compressed from the original source,
and will produce noticeably better video quality.

If however, if your project is HD, than perhaps playing it on your
computer might be beneficial since this would be one of the only way to
play a "real" HD movie.

Some times there are simple benefits to using a cheap 40 dollar DVD player
to do a simple task.
