Alright. So, my old drive bit the dust. My TS-L462 junked out, and I always wanted a DVD burner, so I took a used UJ-820 and slapped it in. It plays cds fine, but when I play dvd's, they dont work. The sound plays, but the video doesent. Also, my DVD burner is not found when I try burning movies VIA WMM. Any help? I've looked everywhere for drivers. No luck. HELP!
