No, the bt848 cards help you lots by copying the data around for you, also the problem with mpeg is that the colors have been stored in yuv format instead of rgb because its smaller.. Most video cards have h/w to help you convert between the two, and under windows this is supported, but XFree86 doesn't. A good mpeg player would use shared mem to reduce the amount of memory copying by a large amount, but its still slower than copying stuff in hardware :) BTW make sure you are using a descent mpeg player.. There are a fw out there, so try some of them and see if it helps. --------------------------------------------------------------------- |Daniel O'Connor software and network engineer for Genesis Software | |http://www.gsoft.com.au | |The nice thing about standards is that there are so many of them to| |choose from. -- Andrew Tanenbaum | --------------------------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
