I have a Dell Inspiron 9300 with a SATA DVD drive running Fedora Core 5. My DVD drive mounts as /dev/hdc (not an sdX device). Since it mounts as an hd device it cannot have DMA enabled thus access is too slow to play a movie (movie stutters) and when copying a large file from DVD to hard drive my whole system bogs down until the copy is complete. I've read that this is because the DVD drive is SATA and not supported yet, and there's a buggy work around involving editting libata.a and recompiling the kernel. I remember trying this in Fedora Core 4 and it was very unstable. Is there a fix yet in Fedora Core 5 that is stable?
