Appreciations for your replies, JimH and swiv3D and,
Apologies for my much-too-late response
I just downloaded MC24.0.48 and it worked!
At least for one video I tested (.ifo).
Thank you so much!
The strange thing is that, I' d attest under oath if you wanted,
that I used the same procedures outlined in my previous
query.
If this is in fact the case, I'm puzzled as to why the same result
does not always follow.
As for the solutions suggested by JimH and swiv3d,
I think Defender is disabled because I get a warning message that
it is -or is it a fake message?-, and just temp disabling Noroton works;
but, in order to dissolve this problem, and in order not to experience
scary moments, I'll try to tweak my Norton settings.
Thank you again and do have a pleasant evening.
TT
