Hi, Just set up my TIVO for the first time. Output via SCART is excellent, however output via RF is very very fuzzy and unwatchable. I've got a cable RF feed coming into the RF in, initially I had some problems with sound on terrestrial channels (via RF) however this seems better now I've improved the connections. However, the RF Out is so bad, I've tried many different channels to ensure there is no overlap but had no luck. Is my RF module boken? Can it be replaced? ANy help would be appreciated.
