Engadget, TiVo permalinks for TV shows?:

Microsoft, if you�re listening, you�ll add this feature to Windows Media Center when you roll out MSN Remote Record.

While I don’t believe it is tied into MSN Remote Record, folks interested in permalinks to Tivo shows should check out our SDK on ‘Click to record’:

Microsoft� Windows XP Media Center Edition 2005 includes a feature called click-to-record that enables applications to programmatically schedule the recording of TV programs. Click-to-record can be invoked in the following ways:

• By a hosted HTML application or add-in running inside the Media Center shell.
• By an external application using the managed click-to-record application programming interface (API).
• By the user launching a click-to-record document from the Windows shell.
