Most "library" Movies are $10, new releases are $15 unless you pre- 
order or buy them in the first week then they are $13.

In the end you are getting near NTSC resolution (with a frame rate of  
24p) with decently high-quality encoding (and of course stereo/ 
surround) audio). Most folks won't notice much of a difference  
between what you get and your average DVD. It is a simple matter of  
balancing quality / resolution against the fact of how large the  
downloads would be. If you jump up to 720P then you are talking about  
an increase over 2x in the data rate assuming you maintain similar  
level of compression in the encoding.

Recall that your average DVD uses MPEG-2 (which isn't as good as H. 
264 at the same data rate) and it could even contain video encoded at  
352x480, 704x480, or 720x480 with a similar dropping of vertical  
resolution to allow wide screen formats.
