Excellent gomezz, many thanks. So without a freesat enabled tv set I could not guarantee recording 2 whilst watching a 3rd, as I can with a free view enabled set. That really shouldn't be a problem. A bit off the subject I am truly amazed that for the 3rd week running the freeview signals in the S.E corner have been unwatchable. I think our switchover is due in June and if things don't shape up after that it will be clear that we've been well & truly taken for a ride and time to get a dish. Thanks again, there was me thinking a transponder was one of those things that they used on Startrek to beam people around.
You can't guarantee recording two and watching a 3rd on your 9200 what you can watch depends entirely on which channels you are recording. Try Recording BBC1, ITV1 and watching ITV3.
Digital TV multiplexes multiple channels onto a single carrier frequency (The same single carrier with Analogue carries a single channel). On Freeview these are known as MUX. Post DSO on a transmitter with full Freeview service there are 5 SD MUX and 1 HD one. Satellite is the same except that the single carrier is known as a Transponder, there are dozens of these instead of only 6 so each one has less channels than Freeview.
Because Humax tuners can demux two channels at the same time from a Transponder/Mux the following determines what you can do
Recording two from the same transponder/Mux - you can watch and use time shifting on any 3rd channel
Recording two from different transponders/Muxes - you can watch any channel sharing a transponder with either recording.
Open this file in your browswer.
Look at the coloured blocks in cols 1-4, these show you which channels are on which transponder, using this and the above rules it's easy to work out what 3rd channels will be viewable.
For instance recording BBC1-HD and BBC-HD you can watch any other channel and even pause it live. Recording BBC1-HD and BBC-HD only uses 1 tuner.
