Stall during saving? Possible solution.

Every time I tried to export my video, no matter what the
format or quality, my save would stall at 63%. I've got
loads of RAM, a nice processor and plenty of room on the
hard drive. It's a pretty complex video with maybe 150
clips in 3 minutes so I tried PapaJohn's fix of saving
portions of it in high-quality chunks, then stringing
them together. Well, it stopped stalling at 63% - it
would skip directly from 63% to the end, cutting out half
of the video. No matter what format, it always quit at
the same place, so I tried to really obvious solution of
just removing that clip and making a new copy. It works
now, so... if your save stalls, check the clips. Who
knows why the stupid thing does what it does..

Increasing the virtual memory also seemed to help.
