I will mail you a zip to one now.

File received and examined. Data is somewhat unusual for Mac editing in that it is ATSC Standard A/72 Part 2:AVC Video Transport Subsystem Characteristics
H.264 Hi Profile Level 2.2 15 fps CABC entropy encoded video. While this is not the main problem, it is not a typical Mac compression format. The basic problem is that QT is designed to handle program streams and not transport streams. If you look at the QT inspector, you will note that the video data has no defined video data rate and, therefore, no defined video track data size. This is probably what is kicking out the general and out of memory errors in FCE if you tried to move the file to the preview window. It is also why any QT based app will fail to convert the video. VLC can move the audio and video data from the problem MP4 file container to a new MP4 file container that is properly recognized by QT. This operation is quick and easy. Unfortunately, in so doing, frames appear to be re-ordered, rendering motion sequences unusable for your editing. For me, the best results were achieved by use of HandBrake to re-convert the files. I used an RF 0 (100% quality setting) keeping the original frame rate and set the app to remove any duplicate frames if found. Will send you both URLs for your review. Everything else I tried failed.
