On the same subject of the IFO, BUP files.
I compared the output of AnyDVD (stand alone) / AnyDVD+CloneDVD / AnyDVD+DVDDecrypter to realise some interesting differences. The reason I did the compare was because of 2 problems that led me to investigate. Problems described later on.
The movie was Star Wars III (Revenge of the Sith).
Basically I saw that the files from AnyDVD ("rip to disc") were different from the AnyDVD+DVDDecrypter (IFO, BUP) in only one byte.
Further I observed that the files from AnyDVD+CloneDVD would then be identical to DVDDecrypter output (IFO/BUP! not the VOBs).
So basically my question is why the Decrypter and CloneDVD IFO/BUP output files are identical and the ANYDVD rips are different in one byte? What is the significance of this byte? Is there a bug?
The output of AnyDVD "rip to disc" with "remove unreferenced streams" on, was unreadable by CloneDVD afterwards when I tried to selectivelly remove streams. CloneDVD would complain for invalid DVD structure.
I have been experiencing a problem with my player (Sony DVP-NS425P). In some cases the movie freezes at some point and I have to skip chapters in order to get it going (popular problem as I see in the forum). I also observed that this happened to ripped files from ANYDVD with "rip to hard disc" feature as opposed to ripped from DVDDecrypter. The media that I used was Taiyo 8x and no program was running in the background. Could there be a connection of those IFO/BUP differences with the video freeze?
