Are there any free DVD decoders (for WinXP)?
(if so, where can I get one?)

Methos-

Would this also be called a DVD processor?? If so, I noticed one at Best Buy today. Price $159.00.

May something from http://www.digital-digest.com/dvd/downloads/encoding_plugin.html

DVD Decrypter is very good.

Or if U mean the Player software THIS comes with most DVD movies theese days.

Di - In order to store the amount of information in an entire movie on a DVD, they use compression. A DVD decoder is the software (or hardware in some cases) that decodes this compressed data into normal data so that you can play DVDs (a home theatre DVD does this with hardware, a computer usually does it with software). They typically cost $15.

ivnj - DVD decrypter doesn't look like what I'm looking for. I'm only looking to play DVDs, not copy them. I have interactual player, but I still need a decoder before it is usable.

Tom - Thanks, I'll take a look at that page.

Well, DVD decoders are generally for-fee, due to MPEG-2 licencing.
I did find some DVD playing software for $15. (These plug into WMP, the standalone versions cost more) The links are below:

I hope this was somewhat helpful

I use THIS. And no dvd decoder card.
