The 100% signal is most likely mainly noise. If you look up the skew settings for your location for EB1 and Astra 2 and try setting the lnb about midway. Then tweak for max quality.

Just a guess may be the hdr is downloading the epg twice to recover the corrupted bytes as a result of the poor signal quality.
Just repeated the test I did the other day (result 28 seconds) it took about 45 seconds. Signal now 100% quality 90%. Another theory bites the dust.
Repeated test after a freesat retune with same result.
Is there now something different about the epg, does the boxes on V1.00.13 still only take around 30 seconds (one for Barry :-))
Why did my box on V1.00.15 only take 28 seconds a little while ago ?
For reference CH4-HD currently 90/90% with rock steady readings
