For all the above - thanks!

BUT - we are looking for a simple 'plug and play' type solution.

These 'shut ins' are NOT computer people. We just want to take a 'player' to them, say push this to turn it on, and push this to play.

Thought we had it with the Lennox DVD player!

The question is still this  -

Does any other brand of DVD portable player read MP 4 ?

If we could find one -  our problems are over!
