Just a bit more after a bit of exploring and testing....
I was able to scan and add the other satellites I am interested in using FTA mode. Thank you Graham for the link to the relevant instructions. The box has a fairly comprehensive list of satellites and transponders built-in (current at time of manufacture). I have not yet explored how to add to or edit this list. The ability to edit will be needed because transponder parameters and use changes (slowly) with time (eg DVB-S to DVB-S2).
Channels appear to be stored in the order in which they are found, starting at channel 5000. I presume this is to avoid any clashes with Freesat programming. There does not appear to be any way of re-ordering the stored list of channels (eg to alphabetical). There is a channel editor built-in, but it is only appropriate for use with a few (10's) of FTA channels. Is there any way of downloading/uploading the stored channel list by the network connection for remote editing and re-ordering?
There does not appear to be any way of showing basic information about the channel being watched. Pressing the 'i' button will only show the channel name and the channel number assigned to it, nothing more. Is there any way of showing now/next and synopsis when watching a channel known to have this information correctly available? Is there any way of showing satellite/frequency/PID etc of the channel being watched to aid identification, particularly when multiple regional variations of the same channel are known to be on the same transponder, or if the same channel is broadcast from different satellites?
Thanks,
Peter.
