That's exactly the same problem I'm having Philip.  I'm in Australia and 
it's only occurring  on 3 channels (9, 7 and 10), but doesn't happen on 
2 or SBS.

I am using dvb (two Twinhan DST cards), and it does seem to happen when 
I get poor signal for a second or two (either due to signal problems or 
the back-end not keeping up with error correction).  I haven't noticed 
it while watching live tv, but I don't use the box to watch live tv.
