You may want to try iSquint. It's free and doesn't require QuickTime Pro.
Here are the settings that worked for me using iSquint to convert the LR tutorial videos for use with the Epson P-2000:
- drag and drop the QT video on to iSquint
- choose your destination directory
- set to Optimize for TV screen, Highest Quality (you may try Standard first)
- under the Advanced settings drawer, set framerate to 15 fps, Audio Bitrate to 96 kbs and Audio Hz to 22050 Hz, leaving everything else as is
Then convert (takes a while!), upload to P-2000 and enjoy... !
