Screwy VOB's after Decrypting

[DL]

I have what is a puzzling problem. I was ripping Pocahontas II for my daughter and everything went fine (or so I thought). I found it did not need to be rendered due to size so I went to my DVDMeastro and starting creating an image. I later burned the image and found most of the movie was missing. I investigated it and found when DVDMeastro started creating the image it would go through most of the first VOB and then skip to the second and then within 15 seconds skip to the third. I tossed all of the attempts in the trash and went back to the DVD to start another rip. I sat and watched as the rip took place and found during the first VOB it would stop and the hard drive would go nuts but no read errors come up. After 30-40 seconds it continues on with the rip. When completed all VOB are there so I strip the chapters and it seems to work fine however as soon as I go to make an image the same things happens again. I looked at the DVD and it has no marks or scratches of any kind. I determined within reason the spot DVD Decrypter hangs is the same place the image creator jumps to the next VOB. I know this is nuts but I cannot figure it out. When going viewing the movie at the spot everything goes bad I find what appears to be a scene that repeats itself several times a total of about 6-9 frames (just a split second flash).

Has any had this kind of a problem?

Have you tried chaning the CSS settings? or the I/O interface setting?
I had a simmilar problem, I think, but it was ~6 months ago with a very old version of DVD decrypter and I switched to smartripper and it worked. The memory is sort of vague so I can't give you any particulars, sorry.

CSS settings? Not sure what that is or how to use it if I knew.

Were are they and what do they do. I am using current version of the software.

In DVD Decrypter there are some settings under the CSS menu tab that change the way it tries to find keys for decrypting (I think it is more aggressive but takes longer). Have you tried just copying the vobs from one place to another on your hard drive? - if that works fine then it shouldn't be a CSS setting but you could try messing with them. You should look through all the options of DVD decrypter and figure out what they do, some of them are useful :)

So the 'read rate' doesnt remain (roughly) constant throughout the rip? That would suggest some media/hardware issue.
Only the layer break I would expect the read rate to drop off, but it should pick itself back up quite quickly.
Does the program 'buffer' whilst reading? That indicates a problem with your hdd configuration.

Once you've ripped to the hdd, can you play the vob files straight off?
Do they work ok there?

I seriously doubt this is CSS related.

My system has 3 hard drives and all three behave the same. The program looks to play fine in normal motion. When you move through it by frames you see a number of times (at the point were ripping drops to 0) the scene repeats about 4 frames over then normal then repeats 4 more. In normal motion you do not notice it (just looks like a blimp). The rate prior to stopping is about 8.5x then drops to zero instantly and the drives start going nuts. 30-40 seconds later it continues normally. I have tested it on all three drives to elimate the hardware. I have backed up at least 15 DVD since the problem. Maybe it is a one of a kind and I should just get another copy and try it again.

What do you think.

That sounds like a good idea to me.
If you could test in another dvdrom too, that would be great.

Is anyone finding this true. I have two DVD readers I use for ripping. One is fixed at 2.0x read and the other is 8x. When I use the 8x I get speeds at about 7.8 ~. When I use the other I get 2x as you would expect. But if I use them at the same time the 8x drops to match the speed of the 2x. Once I stop using the 2x it jumps back to 7.8~. I am ripping to two differnt SCSI drives both rated at 160 transfer. Could this be due to the 2x following some industry read and the 8x following suite?

Damn I seem to get all the really bizar and strange things happen to me.

Any thoughts, comments, constructive or not.

I think thats just IDE for you! SCSI makes use of multiple simultaneous IO requests. I dont think IDE has that ability and so when using two devices, its slow.
Try putting your readers on different channels.
