Movie rendering problems bigtime!!!!

I use the programs pinnacle avid liquid 6 and cyberlink powerdirector 4.0.

I was rendering a movie and for some reason, I get to 60% in powerdirector and it gets no further. My system simply stops processing it and I have 2-6% system power in use.

I have no idea what to do short of rebuild the line of clips on the liquid 6 and try to use that to render. Note: I use lots of special effects, color changes, speed changes, and ect and normally, I can render a more complex movie then this but on this one, it simply doesn't render past 60%. If I make the movie shorter, it renders more but then stops at 68, shorter-> 79, and so on till 99%. No matter what, it never seems to render this movie fully whether at 160x200 H.264 Divx or HD 1080p

No difference whether on my personal computer, or our very nice server.

Might not be helpful.... When I have a video problem, I mosey over to afterdawn.

Afterdawn?

Edit: Cool forum. Already asking there.

Say, anybody here use Canopus Edius 3? Heard had a great HD renderer.
