it's the answer to the bug i described in my earlier post hope you gonna finaly fix this now 
did you found a solution on how to make the Crop Window from the Mplayer instance resizeable by 50% to avoid problems with Video Sizes bigger as the Display Resolution especialy HDTV resolutions ?
you should also check your temporary save system seems it fails to save raw ouptut (only) (im sure thats also why alot of people get the Nothing Transcoded window)
# ".\mplayer\mencoder.exe" "C:\Silent_Hill.ts" -vf crop=1920:816::132 -of rawvid

osound -o "C:\Programme\video\MediaCoder\temp\Silent_Hill.ts.264"
this fails for me it gets encoded (it seems so i can see the frames being encoded in the console window) but i get the Nothing Transcoded window @ the end
C:\Programme\video\MediaCoder\temp\Silent_Hill.ts.264 <- the file gets created and grows but @ the end it's deleted and not put into the output folder
and another problem when saving into .mp4 you miss to give it the correct FPS @ muxing input of this is 23.976 fps this is what Mediacoder does when caling mp4box
# ".\tools\mp4box.exe" -add "C:\Programme\video\MediaCoder\temp\Silent_Hill.ts.
264"#video "C:\Silent_Hill.mp4"
Adjusting AVC SizeLength to 16 bits

Import results: 3597 samples - Slices: 133 I 2198 P 1266 B - 1 SEI - 86 IDR
Saving to C:\Silent_Hill.mp4: 0.500 secs Interleaving
you see the problem it gets saved as the standard mp4box PAL framerate that is wrong you have to set the correct fps that's coming from mplayer or mencoder and not the standard fps
