High smartripper success rate... but...

[mojo2185]

Smartripper works pretty darn good, but i've run into problems with three DVDs so far.
Here's what happens...
The VOBs start copying, and it got to 80%, then it pretty much stopped. With a different DVD, the VOBs copied to about 74% and then smartripper froze, and i started getting "broken blocks"
I also noticed, that with these DVDs, they do not playback well on a computer DVD-rom. Most of the movie plays well, but sometimes the picture will start skipping, moving slow, etc... These DVDs however played fine on a standalone DVD player.
I'll be honest, the three DVDs were rentals, so is it possible that those discs were damaged by someone? They're probably not specially encrypted by the rental place because i've copied other movies from the same place...
So what's the deal? Any ideas?
Thanks!

Hard to say, but on my system, I have better results with Smart Ripper when DMA is turned off for the DvD player.

One more piece of info, any DVD that i actually own (original copies), work fine on my computers DVD player. This also leads me to believe that maybe a scuff or a scratch on the rental DVDs is causing the problem. Let me know with any other ideas!

As far as DMA goes, i'll look into that, i gotta figure out where to change that on my computer because i'm running windows XP, and i haven't figured out where every option is yet.

Thanks!

This (again) is probably a bad spot on the disk. These bad areas can usually be seen, IF you look hard enough. Unfortunately, you cannot select the speed to read the disk, so SR always goes "flat-out". Needless to say, at these speeds, errors are more pronounced (less time under the photo detector). This is why the standalone has much less difficulty reading the disk, since data is read off a DVD in a standalone at a constant 22.08Mbps rate (1X). Sometimes, simply cleaning the disks will work (I always clean my disks before I try to read them). Sometimes you need to fill in the bad area (usually a "skuffed up" area) with something like paste wax, so that the laser reflecting off the pits isn't scattered as much. For the most part, the wax is invisible to the read laser.

I guess that we need an option in the rippers to rip certain sections at 1X (or even slower) speeds.
