Jason,
I don't think you can stream video to a standard hard disk from the 1411. The data rate required would be too high. You might be able to do it with specially designed storage, such as Vision Stream (see Graftek).
If you are planning to acquire relatively short videos, you might be able to capture it all to memory and do your conversion to MPEG or AVI, then write it all to disk.
You can't use the 1411 as a Video for Windows device. The necessary drivers aren't there.
