Well its been a long time since I last had to rip a DVD to something that was easily editable so I'm sure the way I'd do it isn't the fastest and best way out there but it works.
Up to you how you rip your DVDs and get your vobs but personally I use dvddecrypter (
www.dvddecrypter.com though the site was down for me, quick google search and you'll find loads of places to get it). Really straight forward program where you select the streams you want and then hit rip (or something like that, long time since I used the program). Though since your DVD is coming from a video production company you should be able to just drag-n-drop them via explorer.
After you've got your VOBs, I use a program called DVD2AVI to convert it to a raw avi which nearly any video editing program can import. I couldn't find a direct site for it but you'll get it at
http://www.divx-digest.com/software/dvd2avi.html. A warning about the Gloval version, there is a file in the zip called "lame_enc.dl", it should be "lame_enc.dll". The program is really simple to use, just open the first vob, it'll notice the rest and link to them as well. Then File, Save Avi then sit back and wait.
It'll give you an raw avi file of the video and a mpa file of the audio. Now here comes the messy part, so if anyone knows a better way please do speak up.
Studio8 wont except a .mpa audio file but winamp will! So personally I'd configure the Nullsoft Disk Writer output plugin to convert it to a raw wav which studio will accept.
If you need me to go into more detail on any points just give me a shout. I'll make a nice guide with pics. =)
