If you have had trouble connecting with your series 3 TiVo to the server (mothership emulator) for a while now and your ISP is TPG and your IP address starts with 193 or 194, then please try connecting again (unless your last connection already worked).
This may also affect other Australian (or NZ?) ISPs which have added new IP ranges in the last year or so - in English, most likely to be an issue for you if you changed to NBN or changed ISP in the last year or so.
