Just bought the external hard drive expander - and installed without a hitch. However am getting the same pixelation and stutter issues others have been getting. Halts and pauses roughly every 30 secondas or a minute making everything unwatchable. Disconnect the hard drive and everything runs fine. Anybody find a solution? Or will I need to return this. It's not a power supply issue.

  The brand new UPS solved it beautifully and it worked perfectly since then. I plugged in both the DVR and the expansion unit into the new UPS.
