The dvd-drive is an atapi triple-speed and I never had problems getting full framerate on the same machine with the same drive in Linux or Windows (and yes, UDMA is on), so maybe there is some kind of inefficiency/weirdness in ata causing all the trouble? Are there any means to influence read-ahead-caching and the like via sysctl? -- Michael Nottebrock To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
