That looks like a 'Hey, Mom, look at me' command line.  What happens if 
you use

ffmpeg -i "Fatal Honeymoon.mpg" -target ntsc-dvd FatalHoneymoon.mpg

or the same but with mythffmpeg?

Does it produce a growing output file?  Is the result off centre, too 
wide, too high?   A quick test on the first minute or two would give the 
answer.  And I would still like to know the result of

ffmpeg -i  "Fatal Honeymoon.mpg"

Cheers,
