I've downloaded this before. Haven't ever gotten anywhere with it. You may be way more resourceful than I though.

This is actually an open source 3D package that happens to have a decent little NLE hidden away within it. I use this program all the time, but I must warn you, the interface is very, unique.
If you try it out for editing I'll save you a half our. When you load it for the first time, look along the top for a drop down menu that says "SR:2-Model" click it and select "4-Sequence" from the list. That is all I can tell you for now. You're gonna hate me, but I'll give you further info if you PM me.
