Hi, Just use the mciSendString command interface. It is completely compatible with Windows 95 and Above. You won't need to include anything extra in your setup file for your program either. The only thing you could run into is, the user may not have a certain codec installed to play certain formats ( eg: quicktime movies) But for the most part. You should not have any problems at all. I have a few things on my website that will help you. MCI tutorial, ect.. Take care.
