I'll tell you guys something. If you want to render big files properly you need a memory manager. I use MemTurbo. I turn off everything except that. Everything. Unplug the net and turn off your firewall too. Have lots of memory I have 512 meg have a big swap file set up I have mine set to 1 gig min and now have 8 gigs free on c drive. Load vue and render. It works.....
