Something else that came up recently on this list that can affect
performance is if your SATA drives (assuming you're using them) have NCQ
enabled. In my case, I had to go into my BIOS and change the controller to
AHCI mode. For me, it helped the responsiveness in multitasked I/O
situations (e.g., copying a large file while myth was recording and/or
playing back no longer causes stutters). Check here for more information:
