How can I make a Windows shortcut to a specific TV channel in Windows Media Center?
This is a couple of years too late for your question, but I just uploaded a project on CodePlex that lets you create desktop shortcuts to specific channels in Windows Media Center (and otherwise, automate channel changing via C#).
You can write a PowerShell script. Something like...
add-type -AssemblyName System.Windows.Forms $proc = Start-Process "C:\Windows\ehome\ehshell.exe" start-sleep -Milliseconds 10000 #Wait 10 sec while Media Center loads [System.Windows.Forms.SendKeys]::SendWait("^T") [System.Windows.Forms.SendKeys]::SendWait("7") #Channel 7
