You said you are having trouble
ripping some DVDs on your Lite-On DVD burner. You also said you can
play those same DVDs on a stand-alone (stationary) DVD player.
My question to you: Can you
play those same DVDs on your Lite-On DVD burner? If so, then you should also be able rip them with the Lite-On. You just need the right software. That is what Spazmogen was telling you.
