For some reason neither Apple Quicktime nor the alleged Quicktime “Alternative” player (which, when I installed it, looked EXACTLY like Apple Quicktime) allow me to change file associations. Which means if I have either of them on my system they will insist on controlling what they want to control, regardless of my wishes. Homey don’t play that.
Therefore, anyone on the internet who wants me to view or listen to media in a Quicktime-only format, can kiss my @$$. Find some other format that plays nicely, or forget it.
