Adobe Premiere 6.5 - problems with imported mpegs

[dc91gt]

I've been doing some editing this past week and have stumbled on a
problem thats making me nuts.

Here's what I've been doing:

A friend has some video (actor reel) on DVD. So to get the VOB into
something I can use, I use dvd2avi then VFAPI them so I can serve
to Adobe 6.5.

This works great. Preview play back is perfectly smooth.

I then export the video after I'm done editing using their mpeg2 encoder,
again works perfectly.

However... if I start a new project, and import these mpeg2's (which play back perfectly in media player, powerdvd, etc) back into adobe 6.5 and
say click the preview button - the video play back is ultra choppy.. like it's
dropping tons of frames. Even after clicking compile and it does whatever it does (re-encode it looks like) - still choppy. Export the timeline to mpeg2
again.. and the exported file is choppy.

It's not a 3:2/Interlace screw up choppy.. it's more like in tmpgenc - the thinning preview option when you encode choppy.

Am I missing something here? or does Adobe just not handle mpeg properly?

thanks
