This is a bug in FCS, it has driven me batshit insane. if you re-connect the files they will render. Also turning off external monitor, particularly if you are using a matrox mini.
This happens to me with normal Proress footage with a title dissolve. Not very demanding, on a quad core Mac pro.
If you have an entire timeline that has gone bad like this create a new timeline and manually set the correct specs. Then paste the old non-rendering timeline in using shift+command and dropping on overwrite. I guess this is similar to the reconnect.
I'm not sure how much of this is voodoo, but it's getting me by.
