SSME only start playing from the edge of the chunk only (either start or end)

 Hi All,

 After a while of debuging, I found that SSME only start playing at the edge of the chunk.

Say, if I set the SSME position to the middle of a chunk and start playing it, it will move the the nearest chunk edge (either beginning or end of that chunk) and start playing from the chunk edge position.

 I really want it to start from the precise position, is there anyway to overcome this?

 I also see this post here http://forums.silverlight.net/p/174099/642508.aspx/1?p=True&t=634752835832470962 which is kind of old since 2010 and no answer yet, so I just re-create it here to refresh the issue. Sorry if this is the wrong way to bring the issue back.

Thanks
