The “My TV and Movies” library becomes visible when using the Media Center Edition (“Freestyle”) variant of some Longhorn builds. The “My TV and Movies” library is a media application for recording and watching TV. The application is an Avalon container and is opened in Internet Explorer by the Avalon Shell Handler. The container itself includes a couple of dll and BAML files as well as a manifest.
In some builds the filesize is noticeably bigger because it includes placeholder images. Although there is also a placeholder image for the guide, this page will always throw an error when clicked. A placeholder for “Watch Live TV” is also included, but the page will just show up empty. In a later version of MyTVapp found in 4008 and 4015, the application will throw an exception.
To open the application run C:\Windows\System32\mytvapp.container or convert Longhorn from Professional to Media Center Edition. This application is present in builds: 3706, 3713, 3718, 4001, 4008, 4015 and 4029.
