some movies jumping scenes problem.

[alexkid]

Not sure how best to call this issue. But I've noticed it on a few DVD's that I've been trying to rip/encode to DivX. I've done many movies, but only recently have seen this. Some of movies the exhibit his are:
American Wedding
Terminator 2
007: Die Another Day
007: Tomorrow Never Dies

I know there's others, but that's all I can think of for now.

The problem is basically that the movie just jumps to different scenes for a few seconds continually. Just jumps to a scene in another part of the movie, then back to where it should be, then after a few seconds, jumps again, then back, etc. Basically it looks like it's playing two threads that start at different locations of the movie and just jumps from one to the other. And during the "jump transition" for about 2 frames (so VERY quick) the picture blocks into the other picture, kind of like sattelite TV does when you change chnnels. I've attached a picture so you can see exactly.

And also, this issue is at the VOB level right after ripping the VOB's using DVDdecrypter. (it's just nearly impossible to do a screen capture from DVD2AVI since it doesn't advance 1 frame at a time). So you can see this problem in DVD2AVI. Which leads me to belive that DVD decrypter didn't do something propperly (my settings are default pretty much) or are these movies using some kind of copy protection that DVD decrypter can't decrypt propperly??

if anyone has any info on this at all it would be greatly appreciated.
thanks

And also, due to the nature of this issue, I'm not sure if I should be posting it in this forum or rather the Decrypting one. Let me know

Hi-

Are you using DVDDecrypter in IFO Mode as you should, and not in File Mode?

my settings are default pretty much

Change to IFO Mode and try again.

remember that a film can be in any order in vobs an contain angles etc. an example is robocop(R4 version anyway) which has the original anmd special edition(extra 15 minutes footage). both use the same vobs of course but they start mid way through the second vob, then they jump back to the first vob(different parts for the 2 editions). angles are usually done together in a vob aswell, so you would have first angles footage and then second and then the footage the same. when next it came to another angle it would do the same again. tracking of what to play is handled by the ifos. that is where to jump to next to play the next part.

hope that explains why just trying to play a vob can show the effects you describe.

I indeed am using DVD Decrypter in File Mode right now.
I will test out those DVD's again in IFO mode once I get a hold of them soon.
What you explained does make sense. I guess I'm still quasi confused since even in "file mode" the main IFO is ripped as well. And if tracking is handled by the IFO, I would think it should work fine even in File Mode. But regardless, I will try it out again soon.

Thanks guys for your help, I appreciate it.

yes it is fine in file mode. the problem is that dvd2avi(since you mentioned it) loads vobs and not ifos. so it doesnt know where to start and where to jump to etc. you need a program that loads the ifo and reads according to the information from that. plenty of them do.

[alexkid]

dragongodz, ok so then it seems that it doesn't matter what mode DVD Decrypter is when you do the ripping.

I've only used GKnot to rip/encode movies. If I am unable to use DVD2AVI to rip these specific movies (since it doens't read the IFO but rather the VOB(s) as you said), what other program(s) can I use to make the d2v project so I can continue to the other steps in GKnot?
Or can I not use Gknot at all for those movies (if it requires a d2v project generated by DVD2AVI)?

thanks again for the help.

You misunderstand.

If you rip in IFO mode (which is what Robot4Rip has DVD2AVI do for you), the .vob set on disk will contain only a single PGC. It is not the same .vob set as on DVD. If you rip in File mode, there is no way for DVD2AVI to ensure it is getting a single angle of a single PGC, which is required.

You must rip in IFO mode to use the resulting .vob set with DVD2AVI.

If you have ripped it in File mode onto disc, you could then use the HD .vob set as source, but with another IFO parsing ripper, such as VstripGUI. You still need to parse the IFO and create a new .vob set that contains a single angle single PGC. I don't recommend it, as VstripGUI is a complex tool to use without in-depth understanding of DVD structures, which you don't yet have.
