I have a NEC2500 drive. It worked pretty good until yesterday. I was able to watch movies and back up my own collection. I'm using Herrie's latest fw and everything was going nice until I went and purchased some new dvd's yesterday. Now I have no sound on my system. It plays the movie but I have no sound. I'm using a laptop and even that dvd drive has no sound with dvd. I tried cd's and they still work. I've even tried some back ups that I had already done and there is no sound. Can anyone help? I'm running xp on my system. I've tried decrypter and shrink on them. I don't think it's a problem with these programs being that I don't have any sound in regular playback also. Thanks in advance.
