Convert to swf and other Flash questions

[Richard Miller]

Is there a way to convert a .avi or .mov video file to swf in Rev (or  
in the background via Rev control)? Tied in with this is the  
assumption that the preferred way to display video in a browser is  
with Flash. I know streamed Quicktime works fine, but my  
understanding is that one can't assume the user has Quicktime  
installed, but almost always has Flash installed. Is there any  
disadvantage to using Flash versus Quicktime for displaying videos in  
a browser?

Also, with a Flash video, is there a way to step through it (when  
it's displayed in a browser) one frame at a time?

Thanks.
