!!!!SOLVED!!!!
Here's the deal: iTunes, for some inexplicable reason, cannot fix this by editing "Media Kind", in "Options". However, Doug Adams' script "Make Video Tags v1.2"
does fix it!
In Front Row, not only are the TV shows gone from "Movies", they correctly appear in "TV Shows" with their proper titles. For example, episodes of "All in the Family" no longer appear under "Untitled", but under "All in the Family"

This has been busting my balls for quite some time, and I can now finally watch my hundreds of TV shows and movies in Front Row... again! Doug Adams is a frikkin hero!!
