That page is an html webpage.
If you browse to "...\Media Center 14\Data\Default Webpages\English\Playlists" you can find the files.
If you create a new folder path: "...\Media Center 14\Data\Custom Webpages\English\Playlists"
You can create your own webpage there and MC will display this instead.
I posted similar steps to achieve a start page that integrated better with my chosen skin in
this thread.
That's as much as I can help with as I know as much about html as I do about what's wrong with my wife atm (wimmin!!)
I don't think we can code links to playlists in an html page though, which is a shame. You never know though, there's a couple of web apps on the go in third party... maybe one of those guys knows some tricks?
