It looks like he/she might have been krayzie enough to use TheFluff's perl script @_@. Which I'm fairly certain wasn't really meant to be for actual use, just something he was toying around with
. As you found AviSynth simply can't load that many commands at once...if you really want to use that script you'd need to break the Trims up into multiple scripts.
However are you sure you should even be using that perl script? What are the timecodes for the source file itself? If it really is fucked like the example I gave, my suggestion...find a better raw.
Do not let someone provide a raw for you. Who better than the encoder to choose what they are going to work with, and the quality of the audio/video in the raw?
