Well, I stand corrected. I tried decrypting in my Acer 5560-7414 laptop with a Panasonic DVD drive and it decrypted without a hitch in 26' 19" (no riplock). All I can figure is maybe it did not do so in my tower unit (although I rebooted after 7200 update like with the laptop) because somehow it had trouble with the riplock-disabled Liteon drive in it that I normally use.
Successful logfile zip attached. Successful rip to ISO, using "Clone DVD" on CloneDVD2. Will try to re-rip doing "copy DVD titles on CloneDVD and see if that somehow hamstrings the process.
Hm...cannot attach, since logfile is 201.+ KB and forum limit for zip attachment is 195.3 KB.
