The Roamio is easier to use and the software lets me watch any show I transferred to the Bolt, without actually using the Bolt. I am trying to clear all the shows from the Roamio for various reasons, including the tech support's recommendation that the Roamio be replaced because it was making so much noise. The last time I watched a show on the Roamio which was stored on the Bolt was Sunday afternoon. Yesterday when I transferred shows using the desktop, something didn't look right. When I checked to confirm the shows transferred so I could delete them from the Roamio, the Roamio told me it couldn't find the Bolt. I turned on the TV connected to the Bolt and went to settings and then network. It told me I was using the Ethernet and I could switch to Wi-Fi. I did that, but how did it end up switching? If Wi-Fi had been a problem (a tech support person had told me earlier the signal was not very strong) I could have switched my Series 3 to Wi-Fi and used its cord.
