Playback Technologies and Standards "Salad"...
Since WS.WebTV playbacks videos using current Web video technologies (Flash and HTML5) on a variaty of devices (PCs, Mobiles, etc.) and on a variety of Web Browsers, whose combination also condition the playback technology used as well as the formats (H.264, WebM, etc...) - among others - then the video support depends entirely on the combination of those factors: Device + Web browser + Playback technology.
Below you will find a reference table table with the supported video formats, protocols, technologies, etc.

As you ca see, as for today, the safest "bet" is the MP4 (H.264+AAC) video format. In the following document we explain the general considerations when encoding in this format:
