Thank you Clueless.
I experienced exactly what you described but it was so strange I didn't know exactly how to describe it.
I could drag back the scroll button and see parts of the video I'd never seen.
I will check out Rosetta. Thanks.

Thanks also to whomever suggested VLC viewer.
It worked as promised.

I know it sounds ickey, but thanks again for y'alls help.
To have a group of wizards, white knights, gurus, out there doing their best to answer any yahoo's questions is mind boggling.

I have been teaching high school English for almost 30 years.
I was trained to teach the faculty how to use the Mac Plus when it was state of the art and have been "bi" (Windows at school, Mac at home) for the last decade or so.
I have done uncountable favors over the years, trouble-shooting for others and I guess I'm finally getting my "goes around, comes around".

Thanks again.
