Sling Media has added loads of remotes for the new Japanese market. Now Toshiba D-TR1 is officially supported but the skin is a generic one with a lot of tiny unused buttons and some buttons are missing. I will keep using my skin.

The skin I made is a bit too big, but shrinking the size takes a quite a bit of work so I rather live with this one.
