If you are not interested in HD, SD channels still on work on OSCAM line. I do this to record my mums shows. She does not care about the picture quality. Its way more reliable recording on satellite than IPTV.
I set the HD channels equivalent to record on IPTV and it works like most of the time but if it fails the satellite works as a backup and that is always reliable.
A twin tuner box will allow you to record one channel and watch another to record a freesat channel or whatever channel you want.
