WebTV allows a person to browse internet sites using their TV and special equipment.  Recently WebTV changed its name to MSNTV and is part of the Microsoft Network.

We have not tested calendars with WebTV but have received reports that the calendars do not properly display.  This is likely to be a function of the browser which has a reduced set of functions inorder to operate on the TV. 

There may be upgrades available to the MSNTV browser available from Microsoft and we recommend checking their web site often at msntv.com
