Hi Doug, I found that when I went to play it windows media player says it's got an extension (.mpg4) which it doesn't recognize but will still play it. Probably a basic or older version
of WMP although I've found that problem now and again for years. My TV satellite receiver records in an odd format (TS) so I had to get a converter app
for that (along with an FLV converter)
My new-ish HP Pavilion 23 -Windows 8.2- converted all my MPG movies from my 2TB external HD- previously from Vista
, into FLV format without being asked to, when I first plugged it in😠😠??). Pain in the butt having to convert things, don't know why the world doesn't standardize, would make life simpler!
