Wide Screen Production

[David Thrasher]

My Canon Elura II MC camcorder has a feature where it can shoot in a 
wide screen mode. According to the manual it is anamorphic and it 
appears that the aspect ratio when it is stretched out to normal 
proportions is supposed to work on the new wide screen televisions. I'm 
not ready to use this feature yet but I did have a few questions that 
perhaps somebody might have the answers for:

Is there any plug-in's available for iMovie that would take that 
anamorphic image and convert it to a wide screen letterbox format?

Is the aspect ratio the same or similar to any of the standard motion 
picture wide screen ratios? (Panavision, Cinemascope, etc.)

Is there any such thing as a "pan and scan" plug-in or utility that 
would allow you to stretch out the image to normal proportions and 
selectively crop it to fit a standard television screen (4:3, I think)?

Even if I don't use it for any serious productions this does look like 
it would be fun to do something with.
