Sounds like digital distortion, staircase effects etc.

Sounds like your aerial cabling is a little marginal... good enough for
a strong receiver but not quite there for a slightly weaker receiver.

Can you take the HDHR to someone else's place with a great signal and
see how it works?

There's a bunch of aerial installers, but they all cost money.  However
you'll get the best signal possible, in a lot less time than doing it
yourself.



In a perfect install you'd have a single aerial per device, with no
splitters, and one single run of cable with no sharp bends and no joiners.
