You can let web tv users enter your room if you create the chat room that loads into the same page. The “popup” window and the “direct link” will not work with webtv. I used a web tv emulator to test this so I may be wrong as it was not a real web tv unit.

I suggest putting the login that loads into the same page on a seperate page for web tv users to use and keeping your current logins if you have a room already.

Enjoy!
