While analyzing an AVI file with ffmpeg, I get the following error messages:
--------------------------
error, non monotone timestamps 6000 >= 3000
error, non monotone timestamps 12000 >= 9000
error, non monotone timestamps 18000 >= 15000
...
--------------------------
Could somebody please explain to me:
1. what do these error messages actually mean
2. Is there is a way to fix them programmatically?

By the error messsages, I'd say that timestamps (or actually frames) in the AVI file are in the wrong order. Ffmpeg may output that when it spots two frames with the second one having an earlier timestamp than the first one. In your case:
...
Frame N: timestamp=6000
Frame N+1: timestamp=3000
...
This definitely shouldn't happen in an AVI file. I'm sure you can fix the error using a tool like mencoder, though.
Mencoder is a part of MPlayer project: http://www.mplayerhq.hu/
As for the command line, I'd use something along the lines of: mencoder input.avi -o output.avi -of avi -oac mp3lame -ovc xvid
Of course you can choose other output codecs or format. If this doesn't fix the problem, there are plenty (more than I can even hope to name here) of troubleshooting options in mencoder that can be applied by trial and error.

Never seen that one, try this
Gspot is a very neat tool to analyze video and audio, it will tell you what codecs were used, once it's analysed it look down to the bottom proposed codecs and solutions
click on the 1 for video then two
It shoudl tell what the problem is
here's a small guide
