Remember hearing rytec mentioned a lot a while back for cable epg setups , but more recent times hear about epg refresh , a relative has epg refresh on but when i looked at it seems to fill in very randomly was hardly anything there but steadily filled (in parts) as day progressed the settings for daily updates and times seem different to , question is does the rytec way still work and update in one go rather then filling in on the go (set a am update) , a little advise how to set it if Still works would be appreciated thx
