I only just now came across this thread. If any of you are still interested. I use 3ds max, and I just got my model into WED with just three simple steps. Export as .x (You need to get the PandaDXExport for max); Import into MED; Save as .mdl - Done. You will have to do all your bone manipulations in MED though. I just found this out and thought I'd share. Hope it helps someone.
