if you: set the dontuseqt to TRUE
then you will only be able to ONLY play MPG (1), SOME AVI and MOV files with 
"ancient" codecs in LC via: play vc "path/to/videofile.mp"

Thank you for your confidence, but sorry, I cannot be of help here.

QT and Windows were never good companions, so you are out of luck because LC 5.5
will always use QT for multimedia playback on Windows.
