Yes some channels can be weaker than others due to variance in transponder power.. Also there are three sats all in vying for the same spot, the Astra techs try to keep them in an optimal position (i.e.. within the same box) but sometimes you might end up with one sat slgihtly outside the optimal position which may effect it's signal strength..

They are more effected especially by rain/sleet/snow.. This is because of the frequency used (roughly about 10-11Ghz) which is a small enough wavelength to be reflected by water droplets.. If though you take the time and effort to orientate the dish correctly you should have enough signal strength to negate such drops in signal power.. With digital the signal has to drop below a threshold for the image to get corrupted unlike analogue sat where snow/rain/low lignal would cause either black or while sparklies to appear sparodically over the entire picture getting worse as the snow/rain got worse.
