Ok, when we had Sky (standard) we had an aerial engineer round who split the signal though an 'split box' type thing that allowed the signal to go into the TV downstairs, and he also fed a cable up into the loft that then came down into our bedroom.
With a special infra red 'eye' thing that is stuck underneath the TV upstairs, we essentially have Sky in two rooms (a cheap version of multi room I guess).
No we have upgraded to Sky+HD and although we are getting a HD picture downstairs, the signal upstairs is not.
Is this because it is an older cable? Do we need to pay for a HDMI cable to go from the split box, all the way into the loft and then down into our bedroom?
Is there a better way to do this or do we simply need to replace the old cable? Will the HDMI ensure a HD signal? Is there a risk it could be a bad picture due to the length of cable?
