try by reinstalling avi2dvd -... tell us what happened ...

I re installed avi2dvd, ran the program again, now it saying ....Avisynth error. Avisynth open failure.
AVIsource: couldn't locate decompressorfor fourcc divx. C:\v2dtemp\avi2dvd_temp\avisynth_script_file.avs,line2.
Anymore suggestions are greatly received

Aw I'm really fed up, tried using avi2dvd with a different movie and guess what, now its turning off my laptop. cant post the log as dont know when its going to turn off. I can tell you its after it starts video encoding. i have uninstalled the program again and reinstalled. Is there an idiots guide to this program
