Just to clarify, with the latest software, and connected to the internet, I am able to scan antenna channels, and then cable channels. I use an A/B switch to switch between antenna and cable inputs. Antenna channels and cable channels both show up on the channel list after scanning, however only the antenna channels are receivable. The cable channels are not receivable when switched to the cable input. If I scan only the antenna channels, or only the cable channels, I am able to receive either.
As I mentioned earlier, when I reset to the original software, and scan both antenna and cable channels, I am able to receive both. This seems to show that the old software will allow both antenna and cable channels to be viewed.
