Ok, not sure if I still have the command line wrong. Not sure if I
incorporated your suggestions correctly. Tried this:

ffmpeg -vsync 2 -async 1 -i 1662_20120226204000.mpg -t 00:10:00.000 -f
mpegts -vcodec mpeg2video -vf scale=1280:720 -an video-01.mpeg.ts

The resulting video was very blocky. Degraded quality from the original.
