I just installed a new Plextor PX-760A for my new Duo Core 2 computer seeing I was having problems with the Plextor 810SA. My problems just increased, I hooked it up to Master, PATA and nothing, I changed the jumper to Cable Select and it now reads. I then tried to copy a movie, the burner said it would take 184 minutes to write, after twenty minutes and only at 5% I figure something not right. I am using Verbatim 18X DVD-R. Now I am totally lost on what to do. Help!
