To all TMPGEnc users like me, I recently had problems loading AVI files to convert on VCD. I also tried with other encoders and simply does not work. Get the Source not recognised.
Anyway, I discovered the problem and it is the Codec version. If you are using the latest version, 4 that is, stop and revert back to version 3.11 and I recoment you use the one on the tools section of VCDHELP under Kristal Studio Pack.

Now that I went back to old Codec all is working superbly again.
