when i rip on my computer, with a normal 5x player, i get rip speeds of 4x or 5x. but when i rip it with an other computer with a pionee 104 dvdr with a read speed of 6x, it will only rips at .8x or 1x if i am lucky,it takes 2.5 hours to rip instead of 25 mins on mine even if the files are on the hard drive.does anybody have any idea what could be causing this ?
