The Media Center Sandbox

I have two questions regarding ASX support:

1) In local testing, ASX playlist seem to work on XBox 360 extenders. Has the previously documented issue of ASX playlist not working on extenders been resolved? Is this now "officially" supported?

2) The MediaMetadata class exposes 3 properties when playing video - Duration, MPAARating, and Title. How do these map to the ASX file? i.e., is the Duration paramater automatically calculated or is it a simple string field? Also, how is the MPAARating specified? According to the Windows Media Metafile Elements reference, there is no MPAARating element in the ASX specification. Should Title and MPAARating be put in the <PARAM> element as custom metadata?

There's limited support for playlists on the extender, as documented in the SDK.  Bear in mind that playlist support isn't implemented the same way on the extender as on the PC - it's not just any supported format that can be played in a playlist - specifically, DVR-MS files won't play on an extender using a playlist for example.

Does the MPAA rating have an actual value?  It could just be erroneous data due to the way the extender code works and not relevant for playlists.

Cheers,
