Go to a web such as
and you can see what programs are carried on each transponder.Code:https://en.satexpat.com/sat/east/28.2/
If all the programs you want to record are on two transponders you can record them all. In the example you give above the answer is no, you cannot record all of those at the same time beacuse they are on more than two transponders BUT if you wanted to simultaneously record
CH4, Film4, E4, BBC1 London, BBC2, BBC4, (all SD) then you could do so with your twin LNB and VU+ Solo2
As an experiment watch live TV on your Solo2. Now while watching a live program start recording it. Now using the channel selection button on your remote start going down the channels. You should be able to immediately watch a different live TV program - now record this as well. Continue selecting different channels - some you can watch and some the box will display a blank screen and say no free tuner. On every one you can watch start recording it. You will find that you are simultaneously recording 6+ channels.
