Using MC 18.0.180 and a Hauppage 2250 with their latest driver, a scan for analog channels returns, as expected, only one: "Cable 3", as fed from the Comcast cable converter. However a further scan for set top box channels cannot proceed because "Cable 3" is not subsequently presented as an "Analog channel on which to receive signal from STB". Only the Composite, SVideo and Video Aux options appear on the dropdown list. Note that TV viewing directly from channel "Cable 3" is possible, except, of course, that the Comcast remote must then be used for channel switching. Logs emailed.
