I want to start using Avisynth, but when I create a script based on the "Getting the best out of CCE" guide and try to load it into CCESP I get a "This is not an avi file" error. The method I'm using is exactly as shown in the guide, ie at the main window in CCESP change to all file types, and select the avs file to open. Where am I going wrong?

I got exactly the same with Version 2.62 - see my post. The answer is you need to get a version that supports avs files like 2.66

You have wrote this : mpeg2source("my_file.avi") <-- wrong function for this type of file. If you want to load an .avi file you should use : avisource("my_file.avi") If you want to load a dvd2avi project you will use : mpeg2source("my_dvd2avi.d2v")
