Enhancements to Xbox 360 silverlight Video application

The application is a TV catchup service that allows viewers to browse through a video catalog and stream the chosen content onto the TV. The application is written using Microsoft's Silverlight (lakeview) ADK and needs to pass through Microsoft's official Xbox Live certification process. There are a number of new features, enhancements, and bug fixes needed including Integration with 3rd party SDK's and API's. The development effort is estimated at about 100 man days with opportunities to roll onto other projects. Full source code for the existing application will be provided. We require the application to be fully tested before it enters Microsoft certification. Support and bug fixes will be required during the MS certification process. Ideally you should be familiar with XBOX 360 development and the MS certification process
