Here's a weird thing... my Triax TR112 SaorView box happily picks up SaorView from Clermont and FreeView from Divis cos of my two aerials etc.
However - it doesn't find the HD Freeview channels - whereas my Panasonic DVB-T2 equipped TV (and HDD recorder) does from the identical setup.
There must be something signalled on the HD FreeView channels that the SaorView box doesnt like - but it happily ingests all the SD FreeView channels & EPG data. Odd.

Another weird thing is that while my Panasonic DVB-T2 HDD Recorder picks up both SaorView & FreeView signals in SD and HD....
My Panasonic DVB-T2 TV only finds the FreeView channels.
There must be some differences in the software that controls the searching/tuning operation on the two devices where presumably some SI/PSI data is being ignored by the HDD so it can 'see' all channels that present themselves - while the TV is programmed to ignore anything other than FreeView multiplexes.
Not really a problem - just a curious observation !

@Briantist - I just performed a manual scan of C52 on the panny T2 tele and it is 100% happy with SaorView.
I just figured how I missed this yesterday - I did a full auto/install tune on that TV yesterday morning around 9am and thought it odd the Analog RTE was still on air and I was really only expecting a proper SaorView box to find SaorView muxes.
I tuned the other devices to SaorView much later in the day - so obviously Clermont wasn't running full power early yesterday morning.
BTW - I have just ordered another DMR-100HW recorder for another room - its last years model at a bargain around GBP180 on Amazon right now - SaorView & FreeView SD/HD twin tuner HDD recorder.
Its all good :)

PaulN: triax 112 doesn't look like it supports DVB-t2 which would explain why you are seeing Ccarn rte and no uk HD

@Pete - I know the TR112 isnt FreeView certified... the fact it picks up anything is a bonus, but I understand that SaorView is a DVB-T2 system... perhaps a subset of all specs which is why FreeView T2 boxes can ingest the SaorView channels but not the other way around ?

Saorview is NOT DVB-T2, its DVB-T/MPEG-4.
Freeview SD is DVB-T/MPEG-2
Freeview HD is DVB-T2/MPEG-4
So a regular saorview box will be a DVB-T box which will support mpeg2 & 4. Thus the behaviour you are seeing on your TR112 is expected - no freeview HD because it doesnt support DVB-T2.

@Pete - Thanks for clarifying... My knowledge of the NIMM led be to believe that SaorView was also DVB-T2... I hadn't looked at the small print of DVB-T to realise that MPEG4/H264 was supported along with MPEG2.
That explains why the SaorView box can only work with DVB-T FreeView muxes.

Excellent reception of Saorview from Clermont Cairn now with the power increase, and actually considerably stronger than Divis at this location here in Jordanstown Co. Antrim.
Also receing the NI Mux from both Carnmoney Hill and Black Mountain, with Carnmoney Hill being the stronger of the two (getting this off the C.C. aerial). Black Mountain isn't that strong, despite Digital UK's predictions, but perfectly watchable with absolutely no break up.
Very impressed with C.C. though.
Happy days !
