Looks like this problem started happening on 7th February. Between then and 5th March your TiVo has tried to make a call 53 times, but only 4 of these calls got through. When the call as got through TiVo has succeeded in downloading all the guide data. CODE=9 just means "number not answering" so this doesn't really help. (NB "last call = never. last successful call = never." is simply a consequence of clearing the server logs - the last 4 successful calls were actually on 14 Feb, 23 Feb, 1 Mar and 5 Mar).
This all sounds like a simple problem with the phone connection - perhaps a loose cable. Did you do anything on 7th Feb that could have precipitated this? It might be that the TiVo modem is failing, but on balance I doubt that. I see you have another (networked) TiVo registered. Could you use that to test out the phone line? Just running a test call a few times should be enough to determine whether the line's reliable.
