I've gotten the impression that USB2 under FreeBSD 5.3 will support 4x well and be OK at 8x DVD burning speeds, although I've seen some reports of problems (failing every third or forth burn) at high speeds, too. If it is possible, consider using Firewire instead: FreeBSD works very well with FW/1394, and FW was designed for that kind of usage (specificly, reserving dedicated I/O channels to guarantee bandwidth for realtime multimedia tasks). -- -Chuck
