Basiaclly SVCD is MPEG2 with some restrictions. Take a look in the mjpeg doc area, there you find the mjpeg-howto which explains how to create the correct format.

Decoding/encoding will lower the quality a bit. Usually you won't notice the difference to much. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This SF.net email is sponsored by:Crypto Challenge is now open!
