Channel five, Five US, Five Life, can't remember the rest, but if I remember right there are five of them
Re- your other issue, just to clarify, what channels can you actually watch and are correct?
If you can get BBC1, ITV, CH4 etc, then the setup is fine.
For the other transponders that have TPS channels names on them, if you don't want them, just delete the channels and rescan.
However I suspect that you need to update your transponder list for 28E, and delete any 'dead' transponders, and rescan all the new transponders ypu have entered.
