I'd check it out.

I already have genre pages templated but i would love
to see how others are doing this.

I currently use 12 faves per page. I have four two level
buttons below the fave icons (Faves-HD, NetworksA-B, MoviesA-B,
Sports-News). each buton will jump to it's page with a
scroll in from the left of right depending on their relative
position and diplay highlighted. The currently selected
button will then display text for it's second tier. When
the second tier is selected the button is highlighted
with a lighter color than the first tier. It is very easy
to adapt from a template given that most customers will
usually only ask for changes to the initial faves and
music channel pages.
