Help on backup , Splitting Transformers 2. Movie Only on Two dvd-5s with Dvdfab

I downloaded dvdfab 6.2.1.8 and am using the free ripper. I have had to disable path player as in these forums to get it to work cause transformers 2 get an error and stops. So with path player disable it worked while choosing title 47 in the "main movie mode". I save it to the hard drive choosing dvd-9. I did this cause this is what I want to accomplish. I want no compression and to put it on 2 dvd-5 disk. My question is, If I run the saved files through dvdfab a second time "split" will it loose quality or is there better splitter software? Take into account I don't want to buy a program. I want to use free software.
