[mythtv] HandleMedia for Internal Player

[Kevin Kuphal]

In working with my media support for MythNews, I'm trying to use the 
Internal player to play back the downloaded media files from RSS 
streams.  If I play back the file with "mythtv filename", it works fine 
and I can view the video.  If I make a call like:

gContext->GetMainWindow()->HandleMedia("Internal", filename)

I get a black screen, the logs show that the player is opening a 
ringbuffer for the file but nothing plays.  It seems this function is 
how both MythDVD and MythVideo play files using Internal but it doesn't 
seem to work for me.  Am I missing something?
