[SOLVED] mplayer/mencoder alternating 24000/1001fps and 30000/1001fps content

I have alternating 24000/1001fps and 30000/1001fps content, and would like to check for the type of combing present in the 30000/1001fps sequences.

Can this be determined programmatically from mplayer's log output?

If it must be done by visual inspection, can I cause mplayer to start playing the file at the beginning of a selected 30000/1001fps sequence?

Below is a representative sample of mplayer's log. Can any of the fields shown be used/converted to position mplayer to start playback?

The line beginning A: gives the time in seconds since the start of the Audio track (A:1773.1) and the Video track (V:1773.1) at which this 29.970 (30000/1001) fps section begins. mplayer can start at that point using the option -ss 1773
