There are not a lot of reviews on VU+UNO 4K, what are the pros and cons between solo 4k and this model, is it just the extra tuner and display screen?

I can only use it with single sat cable to standard Universal LNB connected to motor, is that still possible as it has a FBC tunner and what will be the viewing or sat channels restrictions when scanning as some have mentioned?

As it has 1 x Twin FBC S2 tunner will it allow me to dual record or record 1 and watch one with single cable, lnb and motor as above?

I really need to have a clear understanding on above before buying as I found out that all 4K receiver are FBC tuners that you can not use motors.
