new user some channels scrambled/freezing

[xxmcvapourxx]

Hi i got my box Openbox v5 yesterday and i plugged it in one connection lnb as sky plus has two i have no connection to sky box thats switched off.

i noticed some of the channels freeze (sky sports 5 and sky sports 4 and few porn channels lol)

so i done a blind search with tv + radio and edited channels and deleted the old channels and updated the channel list with October/November/December.

any ideas why some channels freeze after a few mins.
