Uhm, yeah I saw that and certainly understand them wanting to jab at the qt nuisanceware. There are other ways to view/convert and otherwise use .mov and .mp4 files but that would be for another thread. It would require the use of conversion software, then one could play/copy burn to disc...whatever, they wanted. I use conversion software to convert such files. Freeware. But...like I said, it would be akin to a thread hijack where we to carry on with instructions or advice on the matter.
Suffice it to say, one would be much better off using freeware for converting such files, then viewing them using the native Windows player. For the rare occasions that one would bump into some video file that has been created using one of those "other" file extensions, it is much less of a burden on the system to convert those files, than to have qt wresting with the user all the time.
