eric_0012,
Welcome to the forum. You either have a bad press or scratches are preventing the drive form reading the DVD. A DVD standalone player is more forgiving than a computer and this is probably why you can view the movies on the standalone. I would take them back to exchange them and see if you can find better copies
I/O Errors are NOT bugs!!!! (well, not 99.99999% of the time anyway)
An I/O Error is my way of displaying a problem your drive had with the disc or your system config (mainly a disc problem though).
Unrecovered read errors, Seek errors, Servo errors, Focusing errors, L-EC Errors, ECC errors, CIRC Unrecovered errors etc. are all your drives way of saying "I don't like this disc".
Clean the disc, update your drives firmware (http://www.rpc1.org), try it in another drive, get another copy.
