Thank you for your Suggestions

I am now viewing my films again I am using the VLC Media player which as bobnemesis says does what it says. with no Bother
It has a minimal "Toolbar "interface but lots of things on the Menus including a quite good equaliser sound setup section ...Most of the Menus are beyond me But the basic controls are easy to work and I have seen plenty of "Reset to default" buttons should you get in a mess
I have been playing Region 1 ,2 (aka.II(a)) and 3 .Still got to try a Region 4 Disk
Is a bit slow to find(and read) some disks But I think we have about an 8/10 Success rate

Have noted there is no Region Lock on this Program which several other 3rd Party media players have.
This means that after so many switches the Region on the last disk is the Only region that can be played

And you may be able to restore it only by an uninstall /reinstall? If not Install another player

Only interface that needs work (in a future version) is the Keyboard functions Found I could slow down the Video yet the speed up key did not work (not many Slo-Mo steps!)
I'm going to give this a mark of 8/10. Would have been a 9 but for the Keyboard Issues and the " way too Much" settings. which are beyond the average user. Why don't they lock them in a "More advanced settings" menu?
Visuals/ motion are 100% (on full screen) Sound is 100%
