In my experience, MEP 11 has NO sync. capability, and MEP10 only had it with the add-on extension feature that Magix sold separately for a brief time.
I'm still investigating whether or not there is even a way to do it via MTC.
As it is, MEP, for the price, is a great video editor, and it already includes a 'Samplitude lite' audio editing engine anyways, so why not just take the extra step and migrate 'basic' video functionality into Samp.?
It would be NICE if Magix worked this out so that my friends at the high-end studios in LA and San Diego (currently Protools and Nuendo for commercial video production) can see what Samplitude is really capable of.
I'll poke around on the Video Deluxe and MEP forums to see if anyone has really worked this out or not.
