Well, I got DVD2DVD-R (v1.4.9) to find the output folder ("Path not found" error solved by ripping DVD in ISO mode and mounting the image file - thanks thingy). I noticed with MainConcept specified in the encoder tab that the AVS-Script area was absent. With all other tabs set up, DVD2DVD-R started up fine, decrypted fine, DVD2AVI fine, but the MainConcept encoder never came up when the logfile said that the encoder was started (Task Manager showed no active threads either).

If I specify CCE as the encoder, DVD2DVD-R shows the AVS-Script area in the encoder tab, and when DVD2DVD-R gets to the encoding portion, CCE starts and you can follow the progress along.

Has anyone used MainConcept? If so, what has to be done in order to use MainConcept with DVD2DVD-R?
