Find a DVD with two view angles; R2 Ratatouille; fails for me, load it into CloneDVD re-author the main title only, removing the second angle. Reload in again in CloneDVD and the angle is still there minus the frames...! Put that output back in to CloneDVD do it all again and guess what angle still there, it ain't going.
Work around is to use del_angle.exe on the offending IFO, then use CloneDVD. On CloneDVD's output I can do my convertion to AVI. This way works.
I suspect that CloneDVD will remove the frames but not tidy up the frame pointers. I assume del_angle.exe will tidy up the pointers but not remove the frames. del_angle.exe by itself won't work as it acts in the IFO, I needed the VOBs adjusted and CloneDVD will adjust them correctly after del_angle.exe has done its bit. Between the two programs this way works.
You may be 100% correct here, but since PowerDVD does not get upset with the output, it doesn't quite rise to the level of a full blown "bug"; especially considering that it seems to center around only one disk. I'm thinking that at most they may have made some pointer errors (or something) when mastering the R2 version of the disk - and CloneDVD can't quite figure it all out. (And it's not a copy protection issue - so that clears AnyDVD.)
We'll leave it that you "found something strange" to be sure. But it's just as likely that Rattatouille R2 is bugged.
Now if you'd tried a rip with CloneDVD2, and DVDShrink, and Nero recode and only CloneDVD2 had the phantom angle issue - well then you might get more noticed. I suppose if it arises again on another disk - it'll get added significance.
I personally rip with the AnyDVD ripper and then use DVDShrink to rip the main movie out of the AnyDVD rip - so I'm not a good one to say that one or more titles are thusly impacted in CloneDVD. I can say that i've never found "phantom angles" in any of my movie only rips - ie when re-ripping the check box does not return again. But I don't often do that anyway.
Remember, in future testing you do not need to rip with the AnyDVD ripper 1st if you're using CloneDVD to rip the Main Movie out of the disk. They share the same ripper, so you'll save
time just ripping the movie out of the disk with CloneDVD and AnyDVD in the background. Then processing that rip as you see fit.
However if you want to experiment more with DVDShrink or Nero Recode - then you'll need to use the AnyDVD ripper 1st on all disks that AnyDVD reports strucural protection on.
If nothing else... this was a better discussion than most of them.
