why not an aerial box rather than a sat box?

yes you can put video onto the usb stick and the box will play it but usually only if in a few formats like an openbox will only play mpeg or mp4 files,  all other formats need to go through a computer video convertor programme like freestudio

We're choosing to go with a Sat box as we've got a Dish already sitting ontop of us, going to no use, figure we should use it :) And thanks! I'll just have to put my computer to use and convert my avi and mkv's into mp4's :)

Freeview boxes do not work on sky dishes unless you change the lmb to a good quailty single like a triax,sky use a double which has atone switch in it which most freeview boxes don't like.

Hi Warren,

I'm not sure where you got that information from, but it is COMPLETELY WRONG!

I was a Sky Installer for sixteen years, before leaving to go full-time installing Freeview, and have probably connected literally hundreds and hundreds of Freeview Satellite receivers to Sky dishes over the last seven years.

 

The problem with those Sky dual-throat LNBs, is that the L.O. (Local Oscillation) starts to wander after about five to six years use and they have to be replaced, because the I.F. (Intermediate Frequency) is calculated by taking away the L.O. from the T.F.(Transmission Frequency). So if the L.O. wanders the receiver can't lock onto the channels. - Nothing to do with a tone switch.

 

The tone switch is the 22Khz switch which is built into the Sky dual throat LNBs, to switch from one throat to another. - Sky were planning to use Optus C1 (now D3) in the future as a "backup" satellite, after B1 (now D1) accidentally went out of line (and as a consequence, Sky was down for three days) about 10 years ago.

 

Sky have never used that "backup", but if you turn the 22Khz switch on in any receiver connected to a Sky dish with a dual-throat LNB, you will start looking at Optus D3, and certainly won't get any Freeview channels off it.

 

Incidentally, it's LNB, not LMB = Low Noise Block Down-Converter!

Cheers,    Bill.

Yes you are correct,a good installer will change the lmb for reason you have just out lined ,there is a high chance the decoder will play up if you don,t
