Slow speed while ripping?

[sp4m]

Ok... so i'm encoding the same movie again... now the rate is about 1,150 KB/s wich is way better, but is it good? and the buffer is about the same... between 0 and 60 MB so far... Maybe it will help converting the disk to NTFS...

But i read that many DVD writers are locked at 2X or 2.4X CSS ripping speed... has this anyting to do with it? or maybe it's just that my CPU have a pain in the ass shrinking it...
