I'm using XP Pro but I would think it would be the same:
Go to Add/Remove programs and click on the Add/remove Windows Components and then Accessories and Utilities , then Multimedia and under that there should be a Media Player Listed there I havn't tried it but that may work.
I'm not sure if it's Media Player 7 or the Older Style (6.4 or whatever it is, Its all i use to play media files).
STOP...don't un-install yet....got to The DivX Website and download the most recent version (5 I think), it contains the codec that you need to play .avi files...if you have the codec and are havin problems getting the video and sound to sync, then tough lol...that's why mpeg is so much better, i don't care which is smaller.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
