I don't think the disk eject when the rip is done is working. I put in a DVD and it ripped, but the disk has not ejected.
EDIT: Just noticed this error in the log:
Jul 1 10:25:02 MediaServer kernel: blk_update_request: I/O error, dev sr0, sector 8480772
Jul 1 10:25:02 MediaServer kernel: Buffer I/O error on dev sr0, logical block 2120193, async page read
Maybe this is why the disk did not eject.
