Suddenly unable to play certain m4v files

I have an iPad2 version 5.1.1 and a 1st Gen AppleTV running 3.0.2 with the latest version of aTV Flash.  Every night my wife and I have watched spanish news such as here.—juan-jose-padilla-renacer-ruedos/1418662/  using Remote HD from the iPad to the AppleTV.  It has always worked perfectly.   Then all of a sudden it stopped working and displays a message that the format is unrecognized.  I haven’t done any updates recently.  It still works fine on my Gen2 AppleTV upstairs.

I’m thinking an update must have come out recently that is causing me to not be able to dispaly these programs any longer.

Can someone offer suggestions or maybe it’s time for another 1st Gen appletv update to support whatever just got updated?
