I have a similar setup (but I also have a HDPVR). I had to have to
distribute the IO better in order to handle it. I have 3 mounted TB drives
(7200RPM) that I use  for recordings only.
My Backend also has a Q6600 with 2GB of RAM. It could handle 4 HD Homerun
recodings plus the HDPVR, but any recording playback off my backend would
cause #2 to happen (This is purely an IO issue).
