I posted before my goal of having all my home videos available for viewing on my HDTV in the living room.  The XBOX hasn’t quite delivered.  Lo and behold I recently gave my PS3 another try and it does circles around the XBOX! I can view all my MPEG2 video using the free TVersity Media Server application running on my PC.  I can now get rid of all the lower quality .MP4 files I created for the XBOX.  Maybe the XBOX will one day be updated to allow it to stream the same MPEG2 files; or perhaps it would work today if I knew how to set it up better.  I wonder if the iPad with iTunes running on my PC will be able to stream my video; if it can it will probably be limited to what formats it will stream (QuickTime).

I ran into the following error message on the PS3 while trying to connect to TVersity:

Media Server Error: DLNA Protocol Error (501) has occurred.

This thread lead me to this solution on the TVersity site.
