I'm making mov files in quicktime player 7 and need to speed up their playback beyond the 3x setting available in A/V controls. Does anyone know of a free/cheap piece of software that will help me pull this off?

I don't know of any discrete apps to do what you require. But another shortcoming of audio / video controls (low volume audio) can be fixed by first importing the boosted file into iMovie, boosting again and then exporting as a full size movie file. Just maybe: boosting playback speed beyond the QT controls limit could be fixed the same way.

If your QT 7 is keyed for "Pro" use, you can "scale" the content to a shorter duration which will play the audio and video content faster without having to re-compress the data. Otherwise, you can use the free JES Deinterlacer app to increase or decrease the movie speed relative to the source reference speed of multiplier 1.0000 value but requires the data to be re-compressed.
I am using QT7 Pro, but I need the entire length of my video. Can you explain the scale function a bit more or point me to a good rereference for this, as I don't follow how this will help me. Thanks much for your help.

The entire length of the movie is preserved but QT plays it faster. How good it will look will depend on how fast your system is. Audio, if included, will shift frequencies like a tape played at fast speed. The basic work flow is to use the "Add to Selection & Scale" Edit menu option to copy the source file to a secondary file of fractional duration.
Example: if the source file is 5 minutes in duration and you want to play it back at 5 times the speed of the source file, you would copy it to menory and use the "Add to Selection & Scale" option to add the data in memory to an audio or video file of 1 minute duration. This will squeeze your five minutes of data into a one minute file. Then all you need to do is delete the track used to scale the source data and save the resulting file. This method is quicker than exporting frames at a selected frequency from the source file as an image sequence which physically drops frames either in the export or import process to "speed up" the file playback.
