Transcode Problem when using Frame Range

I am amble to transcode just fine into xvid but the audio is off.  I decided
to use some transcode options to try and fix this, but this requires i make
a sample to see if it worked.  I set the frame range to 1000 and 1500 and
turned off the PSU core.  When i do this the transcode never starts.  Here
is the log:

As you can see, i gave it 5 minutes before i cancelled the process and it
never started.
