I have heard from a couple of customers who have run into a problem playing back recorded TV shows after installing Update Rollup 2 for Media Center 2005. In the cases I've heard of so far, the show will display for a couple of seconds and then displays a blue screen with an overlay that says Digital Audio Service. They were able to play the same shows correctly via a Media Center Extender and via Windows Media Player, but not within Media Center.
The customers I have heard from so far were able to resolve this issue by downloading and installing updated drivers for the video card and TV tuner cards on their Media Center PCs. When working on Update Rollup 2, we tried our best to not require any driver updates above and beyond what is required for Media Center 2005. However, there are a few cases such as this where it has proved to not be possible.
If anyone else sees this Digital Audio Service overlay, please try to visit the websites for the manufacturers of your video card and TV tuner(s) and see if that resolves the issue. Please also take a look at this blog post for more information about the root cause of this error and this blog post for more information about another known cause of this error.
If none of the above steps work for you, please install the Media Center Diagnostic Kit from and then run it and gather a system snapshot and send it to me at email@example.com so we can take a closer look.
