try going up or down on the frequency i.e. 300 =300.4 or 299.8 and scan that after each change I had to scan walsall to get bbc hd and itv hd when I live in birmingham
same here tried everything just wont pick up them channels had to get Q5 for tw and the hdmi don't work with Panasonic and some sony had to get rca5 to hdmi cable have you tried scanning Edinburgh 1 (on your dm800 if that's possible )instead of udingstone had a couple m8s near you that could not pick anything up from udingstone on the kv hd box but Edinburgh brought in everything no bother
