"File is not a valid dvd2avi project" - WTF?

I had the same problem a while ago. All I did was re-install my PowerDVD and it worked again. You could try to re-install your DVD Program and see if that works.

Still no go 

Hi! Thanks for the tip - didn't work for me, though. Here's what I did: * Deinstall PowerDVD * Reinstalled PowerDVD * Tried it out - same error * Re-applied the partition mirror, which has an (unused) full windoze 98se setup on it. * Deinstalled PowerDVD and GordianKnot * Reboot * Install PowerDVD (v3.0) * Reboot * Install GordianKnot with all patches * Reboot * Installed DivX5.02 * Reboot Guess what - this didn't work either. :angry: Chaps, I'm off to work now, in a lousy mood. If anybody out there ever had this problem, please let me know. If nothing else helps, I guess I'll be doing a full windoze install. Again. Man, if I ever find out that I can encode in Linux, I'll drop this Windoze garbage like a hot potato. Ciao, Klaus

I don't think I've had that exact problem, but I've had something similar. Try creating a new d2v project from the vobs, this fixed it for me (though I don't know what caused the problem from the beginning).

I had this problem too once. I just uninstalled Gordion Knot. Well, before uninstalling it, do that option in the program to reset the registry settings. Uninstall the program then delete the directory from program files. Restart and reinstall Gordion Knot into a new directory, like "gordionknot2" or something. Apply all the updates, restart, and it should work. Good luck.

I had the exact same "File is not a valid dvd2avi project" error. Came out of nowhere, have been using Gknot for a year, but I did the same thing Karloz1 did and it worked. Peculiar
