Digital TV is much more susceptible to impulse noise -- crappy motor 
scooters and the like driving past will destroy your reception.  On 
analogue this shows up as a momentary white dot somewhere in the image.  
On digital, at the right point in the stream, it can wipe out the whole 
thing for a few seconds as it tries to re-sync.

Best thing you can do is replace all the coax and splitters with 
quad-shielded Belden RG6.

Instead of the old-style connectors (Belling-Lee), use F-connectors 
(including for any splitters) all the way until your receiver, when 
you'll need an adapter.  F-connectors are impedence matched, unlike the 
old style ones.

This is the cheapest thing you can do and it works in most cases.  You 
can do it yourself too if you're handy with a ladder.  There's a bunch 
of sites about wiring up the connectors online.  It's pretty easy.
