Hi and thank you.
Uninstalling quicktime in El Capitan is no problem.
But: how to reinstall? There is no Quicktime in the Mac OS AppStore
Hi and thank you again, Jiendra-
What I missed was: The solution is to deinstall Quicktime Player 10 ...
... and to use instead the old V7.
But - this can only be a temporary solution. Apple/Adobe should make it possible to play videos with the current version of their software.
Or am I wrong ...
Yes you are right.
New quicktime have some issues.
A lot of codec are missing.
