Okay i am trying to go from dvd-9 to 2x dvd-5

I'm going from DVD Decrypter to DVD2AVI as a frameserver to TMPGEnc Encoder Plus as an encoder and then to TMPGEnc DVD Author as an authoring program.

In TMPGENC ENCODER I am using the source range option to cut my frame served file into two files. Then taking each file separately and creating a dvd for each file in TMPGEnc DVD Author dropping in chapters and creating a seperate project for each half of the original dvd (each "source range") Therefore creating a seperate set of .VOB .IFO .BUP files for each DVD. Then dropping Them into Nero and burning two seperate dvd's from each source range.

It worked well for one disk i tried but i only tried one half to one disk just as a test for my method.

I tried it again and i got two disks with the same first three chapters and differing other chapters. The story starts the same on both disks and then picks up where it would have if the disk hadnt been corrupted with the other three chapters on the second disk. Therefore ending three chapters early and losing the last three chapters. What could be going wrong?

I decrypted only the VOB files from the original dvd, should i have decrypted the entire disk (VOB, IFO, BUP) and then dropped those into DVD2AVI to be frameserved?

My suspisions are that the TMPGEnc Encoder / DVD Author part of the procedure is fine and the problem was with the frameserving.

Can Anyone Help!!
