Looks like it lasted a little under year, before failing.Hooked up the new Homeworx HW-180 device today. So far so good.
It's about 1/2 size of the original one. Receives the same channels as all the
other tuners in the house. It recognized the NTFS formatted drive that I had on the old one, and played existing recordings from the old one without issue.
The only drawback I can see is that it doesn't have YbPbR output, so if the HDMI port ever fails, it's basically done. Other than that it seems functionally identical to the HW-150.
