I apologize in advance if this is deemed a repeat post. However I am absolutely stumped by this error message I receive everytime I try and run the HV20pulldown.exe application:

avisynth open failure: MPEG2Source: couldn't open file (C:captured\HomeSample-0001_.avs, line 1)

This happens with every file I try... I've scoured the web for answers, tried installing different plugins for avisynth, etc for most of the day. Is there a magical update or download that I must do in order to make this work? Thanks in advance... I wouldn't even be here without all of your help, just need a little bit more wisdom!
