I don't believe your Neuros device can actually record HD content, can it? The HD-PVR is pretty much the only way to record from satellite or cable HD boxes. This is typically done with software - MythTV is one PVR software but I would recommend SageTV. OTA HD is actually extremely easy to do and free as pointed out by mlord. But the downside is that it only gives you access to a small subset of channels and you cannot get cable only channels like TMN, TSN, HBO-Canada, Rogers Sportsnet, Treehouse, etc. You also have to be located in a city with OTA signals available which shouldn't be an issue in Richmond Hill as long as you can install an outdoor antenna to pull in Buffalo stations and don't have major obstructions to the south.
In my system I have two HD-PVRs, one OTA-HD tuner and one SD tuner using SageTV.
