not sure if this the right place if not then could someone move it to correct area , went to watch the wwe last night it started fine up until 20 mins into it , then was getting constant freezing sometimes for 30 secs , other times for 2 mins , then would come back for 2 mins then just do the same again , all other channels on the same freq working ok with no problem , all other channels that I watch before the ppv came on all working fine , any ideas as to what it could be , used to be ok up until a couple of mths ago , but wasn't as bad as it is now , was thinking of doing a fresh scan to see if that helps , but thought I would ask here first , thanks in advance
