I have 2 Premieres. One an XL4 and the other a normal Premiere 4. They are both connected via hard wire LAN. The XL4 has the guide data OK, but if I go a week out, it is missing on a lot of channels. The other Tivo is fine. The bad one will see the shows again on the 9th and 10th day again. Is there any reason for this? For example I wanted to schedule a show on PBS 710 on the 15th at noon. It just has TBA for that whole day then guide data picks up again on Tuesday. I see other stations doing this but NOT on the other TIVO. Is there a software update I am missing on the xL4? What Level should it be? Can I force it? I did a network connection and the new updated guide data did not resolve this. I did a power OFF and after 1 minute I put the plug back in. So far that did not help either...perhaps I did not wait long enough? Everything else is working OK. What software level should the XL4 be and how do I get it if mine is not OK?
