Thanks Craig - this is interesting.  I wonder if the issue is caused by
some of the qt ports being built off of libturbojpeg and others (I'm
looking at the culprit qt5-WebKit) being built with libjpeg. This gives me
something to look into.  This could end up being an ansible fix plus a
double check in the compile script while bundling the application.

Both Catalina and High Sierra play beautifully

Excellent - glad it's finally working!

Please use a copy from the Sourceforge site.  Those versions have the jpeg
fix in them currently.  I'm going to try to find a more elegant solution to
the jpeg fix before making another push request to myhtv's git repository.
