  yup, that's a start, but i'm not sure how to parse the output:

$ tcprobe -i sample.dv
[tcprobe] Digital Video (NTSC)
[tcprobe] summary for sample.dv, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
     aspect ratio: 4:3 (*)
       frame rate: -f 29.970 [25.000] frc=4 (*)
      audio track: -a 0 [0] -e 32000,16,2 [48000,16,2] -n 0x1 [0x2000] (*)
                   bitrate=1024 kbps
$

  i'm unfamiliar with the output format of tcprobe, so what's the deal
with two different frame sizes being printed?  and two different frame
rates?  how should i interpret that?  thanks.
