I've used DVD Decrypter and AutoGK many times in order to back up my DVDs. Starting yesterday, when it comes to compression, I receive the error message
Video Compression error: The source image format is not acceptable (error code -2).
I've ripped this DVD one other time but I accidentally deleted it. I also get the same error message when I try to rip other DVDs, so the problem isn't with the DVDs.
What could the problem be?
