I purchased a Dvd player/Cd writer several months ago & had not tried playing a Dvd until recently. It came with some Nero software. When I tried playing with Nero or Win media player, & after some advice decided I hadn't got any 'codecs' I down loaded some (not saying from where) but now get the message 'Showtime can not play selected video whilst other applications are in pause etc, please close.' Nothing else is trying to play it. Trying with Media player I get........its encountered a copyright problem. (It reads that there are X number of chapters though, also the disc title appears in my computer) I downloaded & tried Power Dvd. It started to play the initial copyright stuff, then gave a warning message something about Tv out port being enabled, & now is saying copy protection cannot be enabled. I'm sure it's all software problems, but don't know where to start. It's a genuine disc, & I have Genuine XP os & geniune win on dvd (not tried) & nero software. Any pointers , please.
