DrDish:
The shape of footprints differs between transponders and satellites. In 
Malaga RTL-4 and 5 are very strong (51 dBW), but transponders 51 and 53 with 
Veronica and SBS-6 are much weaker (47 dBW). With your 1m-dish and a common 
lnb you could expect some trouble on this weaker channels. Even a better lnb 
would not do much better. Changing to 120cm will give you good performance 
and 150cm would provide you with some left-over for bad-weather.
