Another update on my Mediasonic HW-150PVR:
Amazon.com: Mediasonic HW-150PVR HomeWorx ATSC Digital TV Converter Box with Media Player and Recording PVR Function/HDMI Out (Black): Electronics
Earlier, I reported how I would get an occasional ~ 1 second 'glitch' in the recording, maybe 1-2 per half hour. I ruled out signal strength, it was no worse when I recorded a very marginal station with drop outs all through the recording - it just recorded the broadcast dropouts as well.
But... I bought DW one for Christmas, to put on the upstairs TV, with a bunch of my pre-recorded shows so she has a 'library' to draw from when 'nothing's on'. And I bought a brand new 1TB drive to put on our original PVR. I decided to set the new PVR to record some of the same shows, so I could determine if the dropouts were occurring at the same time on each.
After two weeks of monitoring, we didn't see a single glitch on the old PVR with the new Hard Drive. So I'm pretty sure it is either a buffering issue with the old drive, or maybe occasionally drawing more USB power than the PVR can deliver. I have not gone back to watch the recordings on the old drive with new PVR yet, to see if that combo has any glitches.
FWIW, this is the 'new' drive:

It is USB3, but that's not it, the PVR is USB2, which is plenty fast enough - if the device buffers properly.
