Re: What can be a reason for slow ripping? Issue in question almost certainly has nothing to do with "settings" -- it most often has to do with what the CD/DVD drive firmware determines is a safe speed (i.e. if the drive finds that there's too much disc vibration it can/will limit the speed -- quite possibly for the entire rip). This can also be limited by the underlying disc itself (I forget how this works, but it's some sort of vendor data that's stored somewhere on the disc; also includes things like who manufactured the disc and a bunch of other stuff). Some CD/DVD drives also store in an EEPROM lists of disc IDs/models/brands that have specific capabilities or set other such limiting features. Nope, not making any of this up -- all true. Just stuff to keep in mind in the future.

Unfortunately, I no longer have the original DVD to verify this theory, but since I have a ghost image of the previous state, it shouldn't be too difficult to restore the system to its previous state and test to see if it happens with other DVDs.
Normally, rips start out kinda slow (2x - 3x, then go up to 4x - 5x, sometimes maybe more). When it failed, it started out at 0.8x and then went up to 1x. I rebooted around the 5 mins mark, started anew, and at the 10 mins mark I concluded that it's better to use the other PC, which ripped the DVD just fine in little less than 20 mins.

Constantine, MI | He means That Many DVD-writers have a learning feature that use the 'Disc ID' being used. These are the unique codes of the disc that allow us to tell who made then (or rather who made the dye used on them) and what speed they're designed for, be it 4x, 8x, 16x etc.The learning feature allows the drive to collect empirical data from its actual usage.
I do not think that is your problem
DID you check the Direct Memory Access
check that DMA settings are all set to DMA if available. |
