I have a 16x dvd rom drive. it' some cheap no brand, but it works fine. i'm ripping a dvd using dvd decryptor right now, and it says the read speed is 2.0x (2.825MB/s). isn't that a bit slow? especially when the drive is supposed to read at 16x? is there a way to change it to 16x? also, when i play dvds, it gets slow and laggy, it plays, but takes a long time to read. wat up? can i switch it to 16x?
