Are you backing up the R1 USA widesreen version?
Is English your language of choice?
If yes to both then this is how you do it with CloneDVD2 and AnyDVD running:
Uncheck TS 01 Angle2
Uncheck TS 01 Angle3
Keep Title Sets 02-11 on both backup disks if you want a full backup.
WithTS 01 checked and highlighted split it as follows
Disk 1 Chapters 1-25
Disk 2 Chapters 26-51
Click “Next” to go to page two of CloneDVD and uncheck foriegn languages other than English.
This method will yeald 100% i.e. no compression on both backup disks.
Go to burn. Repeat for the second disk after changing the spit to chapters 26-51. You’re done!
Again, this is for the R1 USA widescreen version although the fullscreen version should split the same.
If you have a R2 or German version it is authored differently so you can use Tru’s method and you will be able to split the angle Title Sets in the same place as the main movie TS.
You cannot split the angle TS’s in the USA version because there are no true chapter stops in the angle TS’s.
You asked for “…more details, please …”. Well, you’re gonna get details! (Holy Big Post Batman!) Following is a paste of a post of mine from another forum which explains it all, in responce to another person’s question on that forum:

But guess what nino23?
As far as Star Wars III: Just like the other two prequels to the original Star Wars, There are not three different full versions of the movie on the disk. That much data could not fit onto a single DVD9 original.
The explaination for the 2cnd & 3rd “versions” is that they are two other “Writen” language TS’s to provide the rolling-text (probably French and Spanish) that scrolls and disappears into space at the opening sequence of the movie. They actually contain very little data (probably only 100 MB). Those title sets then cut out and TS1 is what is actually playing from there on.
BUT because TS2 & TS3 are linked via “angle” to TS1, they readout, in CloneDVD, as the full GB size-count of the movie.
The DVD is authored to send certain, “choice” commands to your player based what is selected in the set-up menu on the DVD. The way it works is that if a Frenchman chooses the French soundtrack from the movie’s setup menu, a command is sent to the DVD player to play, say, TS2 so he can read the scrolling starwars text in his native language. After the rolling-text plays-out, the DVD player is then commanded to swich back to TS1 which is the real-and-only TS which is actually a full movie titleset. And, of course, the French sound track plays for the French viewer from there on.
You can even watch how it happens, as I remember from I & II, if you use the on-screen display of your player to display what TS is being played. Before starting the movie, choose another language from set-up. Then play the movie from the start. Your on-screen display shows that either TS2 or TS3 playing. Then when the other-language scrolling-text opening scene ends, you will see your on-screen display switch to show that it is TS1 playing from there on.
But even without my long expaination, nino23’s solution is the correct one no matter what backup software you use. Just keep TS1 and uncheck TS2 & TS3. BTW I like CloneDVD with AnyDVD and I split to keep 0% compression, 100% quality.
