also remember that css protection slows down the ripping speed
Let me explain. I have a retail dvd that is NOT css protected (monty pythons life of brian, single layer single sided)
using dvd decryptor i can rip files off it at 6.8-14xish speed using my acer 1640a2 (pioneer 116f rebagged)
Now if i try to rip monty pythons holy grail (another single layer single sided but this one is CSS protected) it only rips at 2.4-5ish on the same drive.
Aside from that there are some dvd drives that do rip slower. But doing css decryption on the fly slows it down ALOT (and i have a p4 3.0, 1gb of ram with hyperthreading so its not a slow computer issue)
