that box is much better, I have one of those and have one sat input in and the second one for cable is twin as has an internal splitter, sometimes someone is watching it downstairs and using the openwebif on a android box upstairs I sometimes watch another cable channel at the same time, I dont bother using the record functions but what I'm doing is using both tuners at the same time.
Most sub providers will allow you to use a twin tuner box. Just ask them when you get a test.With just one line from your provider or two?
