Does anyone know if WinTV is skinnable or where I have to look after a skin ?
Thx for help !

WinTV does not support skins, it has the button there, but it says coming soon. Maybe you've to check back later. I can't find anyone who's done a skin on WinTV either. By the way, your avatar and signature are very nice, but the maximum signature size is 280x70 pixels and we can't make any exceptions - your signature will be removed now.
