My cable provider, RCN, has just updated me with a Tivo Premiere. The set was too far from my router so the installer attached a wireless adapter. I didn't notice at that time but the wait time for the guide to come up is annoying--a full five seconds of black screen before the channel list comes up. Once on the guide, the list scrolls quickly. When I choose my desired channel, or hit the LiveTV button, again the screen goes black for a full five seconds (I counted) before the channel/signal comes back on. I thought it might have to do with the wireless adapter, so I ran a long ethernet cable directly from the Tivo box to my router. Same thing. The annoying five second wait. Is this normal for a Tivo box? Thanks in advance.
