Can you upload a sample file for examination?


The error message would seem to indicate the file contains an unsupported compression format while the fact that the files previously played without problem seems to indicate a security or macOS upgrade error trapping issue. At this point I am assuming the files still play in alternative players like VLC and the problem is only associated with QTX and/or QT7 player playback.
