Hi, I followed the steps in the "Elegant Way" at the After Dawn site as recommended by Kotuku - Thank You! I used the AVICodec tool: http://www.afterdawn.com/software/video_so...rs/avicodec.cfm It said that I needed this codec: Xvid Codec V1.2.1 06 Dec. 08 I downloaded it from: http://www.afterdawn.com/software/video_so...cs_and_filters/ Now I can use either Win Media Player or Win Media Center. Thanks to all who responded to my question. Regards Frank G C
