Ooops, skim reading two question and answering them both wrong, sorry.....
Dvd files are mpeg2 files. To be able to view them in WMP you need the likes
of powerdvd to supply the codec to watch it. It has nothing to do with MM.
It depends on which codec was used to make teh file to be able to import in
to MM, it is always best if you can to use .AVI files. So first thing I'd
suggest is to convert the mpeg to an avi and see if that works.
