Thanks for your quick reply. Two titles I'm having trouble with are "The Software Toolworks Multimedia Encyclopedia Version 5.0" and "A Line in the Sand". These titles were bundle with the CD. I have two sound cards, a Sound Blaster Pro and a Roland LAPC-1. However, neither board is physically connected to the CD (I don't have the three prong cable). Instead, I plugged into the ear phone jack on the CD directly into some amplified speakers. I am adimittably naive about the relationship of between a CD and sound cards. I thought you could get sound directly from the CD without any sound cards. If not, why is their earphone jack in the front panel of the CD? An example of a problem with the "Encyclopedia" title, If I chose a JFK speech on the sound index I can hear it just fine. If I chose the SAME speech with an accompaning video, I can see the video but there is no sound. During installation I chose REDBOOK as the sound option. I hope I'm not asking too many questions, any help is greatly appreciated. Ed
