Comparison in negative forms
Solution 1:
(1) is fine, but (2) needs to be in this form:
I don't like movies as much as I do TV shows.
or I like movies, but not as much as I do TV shows.
You can say I don't like movies as much as you [do],
but if you want to make both parties' opinions negative, you have to use dislike *(or a synonym of it).
(3) I dislike movies as much as you do.
(4) I dislike movies, but not as much as I do TV shows.
