Thanks Steve,

I have been playing around with her MP4 and adding some [converted, 
using VLC] video clips from youtube.
Sometimes they play and sometimes I get the 'File Format Error' message. 
So it looks like I will have to try the 'format' method you recommend.....
I'll let you know how it goes.

BTW The MP4 in question is labeled as an MP5 (it has a built-in camera) 
- but I can't find anything on the unit or the box, or the user manual 
giving a manufacturer's name. The only thing noticeable is the MP5 logo 
- you can see something similar here (although ours is more like your 
chipod but with a 2.4 inch screen):
