glitching

for some reason i am getting bad glitching on bbc1 which has never happened before,also on discovery channel,done rescan but no difference,is this still blow back from other day or just me.

These channels are OK, BBC in your area may be having problems or its your feed, check VM feed cables/splitter.

checked everything, done a rescan again direct from wall,but channels 1-5 now badly glitching

Remove the splitter no need for net connection for FTA channels then try 1-5 channels, as said it could be a local problem in your area, unlikely scan will help.

ok will try,bit puzzling as to why the FTA are glitching,usually they work no matter what

Working again seemed to be affected by the ethernet cable for some reason,changed it and moved the port on router and all is well.
