Anyone have any luck using QT7 Pro license key with Lion? I have one that I paid for many years ago, and while I was able to figure out getting QuickTime 7 installed in Lion, when I put in my registration key it simply says its invalid. In short, the only thing I use QT7 Pro any longer for is to convert, via passthrough conversion, MKV > M4V. It makes it quick and easy to convert MKV's without going through a full transcode with Handbrake. Any help on either front would be appreciated.
