Hi TT

Maybe you can use the win32-based frameserver AviSynth for streaming the 
frames you are interested in into MEncoder. Some work was made to get 
this working. Get a MinGW binary from 
http://oss.netfarm.it/mplayer-win32.php and get some descriptions from 
doom9 forum, e. g. http://forum.doom9.org/showthread.php?t=133114.

A tool for writing the AviSynth script is e. g. 
http://forum.doom9.org/showthread.php?t=129385&highlight=mencoder

A short example script for cutting out commercials is given in the 
AviSynth documentation 
http://avisynth.org/mediawiki/Script_examples#Example_1:_Cutting_out_commercials.

Hope this helps
