Well maybe something in the drive has become loose and it is bumping something while the disc is going into the drive? Also does the jerk sound serious or like it is hitting something? Also, if you want to replace the DVD Drive then purchase one that you would like, (whatever fits your budget and does what you need it to do. I.E. Play DVD's burn CD's or Burn DVD's and CD's etc.) then once you have it, you need to unscrew the case and get inside the tower (the box) then disconnect the cables connected to the drive (Make sure it is the DVD Drive and not your Hard Drive!) and then unscrew the screws holding up the DVD Drive and then you should be able to take it out of the computer. Now, do the backwards process for installing the new DVD Drive. Mount the DVD Drive into the same place where your old one was and then screw it into place, then connect the cables back in and then close up the computers case, and there you go, it should be useable now. But, if you dont feel comfortable doing this yourself, then take it to your local computer store and they shouldn't charge you much to install it for you, especially if thats where you bought the new drive from. Or alternatively you could get someone who knows how to install one to do it for you. I know this was a lot of information but I hope this helps you a lot!
