The best way I've found to circumvent Macrovision and several other copy
protection systems is to use a program called DVD Decrypter. It's widely
available for download from a lot of sites - just do a Google search and
you'll find it easily enough. This program converts the encrypted program
stream on the DVD into an unencrypted MPEG-2 IBP-format file which you can
then import into Premiere or any other video editing software which has
MPEG-2 codecs installed.
Whether your use of footage and/or stills extracted that way is legal or
not is, of course, another question...
