I have an HP laptop thats a few years old. It had a removeable base, with a disc drive in the base, the laptop itself has no disc drive.
Anyway, I broke the base, so I just have the laptop. I ordered an external DVD player/disc drive. It plays the movies, but the films are choppy and keep jerking,stop-starting, its the same in windows player and vlc player. I downloaded a load of codecs, k-lite, but its still quite bad. They used to play fine when I used the base-drive with the same laptop and players. I don't know much about graphic/sound cards, but I know the laptop can handle movies because I have good quality movies on the hard drive that play fine. I would appreiciate if anyone has any ideas.
