Windows Movie Maker Issues

I know it's not a pro-grade program, but it served me well in the past. But now it wants to be gay.

I made this vid with scenes from Tekken 5's intro with music from Devil May Cry 3, altogether a 5min+ vid. Except when I save it has a movie, it only saves about a third of it (3min+). What the heck is going on?

No such option. I could erase it and download it from some official source, but no need. I'll just let it be for now. I posted the unfinished vid anyway. Think I'll give the WMM stuff a rest.
