Out of curiosity John, how many recordings work for you vs fail? Just 
curious, I'm running 2x HDPVR(1) with Bell ExpressVu and have almost 
zero failures. I also get a few channels via HD-Homerun (OTA) and 
occasionally have signal issues with those recordings, but, 
knock-on-wood, the HD-PVR's have been doing fine? Of course I also 
refuse to update (the OS, currently running master for Myth) the slave 
backend that the HDPVR's are on, just in case it breaks something.
