I'd recommend checking out
www.videohelp.com. Some excellent reviews of
freeware and some great tutorials. Also, afterdawn.com.
I'm *assuming* these aren't copy-protected DVD's? If they are, you'll
need additional tools to defeat copy-protection, region restriction,
etc. Perfectly legal in most cases, where you own the DVD's and are
only doing this for backup. Your local/national laws may say otherwise,
however.
Good freeware tools for *that* [not to CD-SVCD] are: DVD Decrypter and
DVD Shrink. See above sites on how to use.
