"Timed Out" message trying to play .mpg files on my STB

[Abuelo]

I recently downloaded the new version of Media Manager that plays videos.  I have a lot of .mpg files from home movies taken over the years.  They all play in the Media Manager on my PC, and the thumbnails show up on my TV with the Home Media Center STB.

But when I hit "OK" to play an .mpg clip, it first says "wait for up to 15 seconds for file to load" and then says "timed out; try again".

The Media Player menu that shows on my TV has a "FiOS Sample Video" (a 20 second clip that starts playing about 3 seconds) that plays without any problem.  The home movie .mpg clip I tried to play is a 12 second clip, but it always times out.

My PC is six feet from the Verizon wireless router, but I don't know what the bandwidth is to the STB.  My Internet service is 20/5, but when I test it I get 10/2.

What am I doing wrong?

Thanks in advance for any suggestions.

i heard you have to rename certain files to play.  try renaming it to mpeg instead of mpg
