Thanks.
There's a plugin here called MPEG SoftEngine that supposedly allows import of mpeg2 into Premiere as well as export. It's possible it doesn't work on version 6, however, because I couldn't get it to import, only export. I think you have to copy the m2vimport.prm file into the Premiere Plugins directory.
If anyone else tries this and has success, please post what you did, it'd be appreciated.
