Yet another video concern !

[MarkinLA]

Hi again.  I completely respect everyone's assistance over my pix/vids concerns. And yesterday I thanked everyone and claimed I now get it.. But (you knew that was coming !) I can not find one actually moving/animated Youtube video.. I search 'videos' and only still-pix appear.. Is this due the same explanation about the major program-crash in the past; that lots of content was lost then ? What is the reason for little if no moving pix ? Am I not selecting them correctly ? Or is it that there simply are little to none ? 
Apologies for my continuing new-guy stuff, Mark
