no box needs a vm signal for box to work and the lan to connect to decrypt the channels,saorview is an irish service picked up by aerial on roof/or cats ears antenna type but is on a mpeg4 and cable boxes are on mpeg2.
the kv750 still works in uk only if you have bought the iconnect to hook up to internet
and have the latest file.

no cable boxes have worked in irl for nearly 2 years,it still works in uk as they are still on mpeg2,irl are on mpeg4 and nagra3 on cable is why no cable boxes work=no fix.
yes a combo box that has mpeg4 decoding for saorview preferably hd if you have a hd box,and sat tuner which you can get the fta like bbc1 hd,bbc hd,ch4 hd and others,onre thing that lets the boxes down is the epg [electronic program guide ] which is 7 days for the irish service but now and next for the sat,not much use if you want to set a timer recordings in advance for use with an external hard drive.
some boxes can be updated to use card sharing and sub to open up all the channels,via a paid sub.the saorview side may need an indoor digital aerial or one on roof pointing to correct transmitter depending where you are.sat boxes need a dish pointing to astra 2 or a motorised for more sats depending on location.
