Are you planning to do your service guide via the phone or over a LAN? If you are doing it over the phone, then there are considerations when working with a VoIP phone service. You have to slow down the TiVo modem using previx codes (sorry, don't have them handy right now). I went through this when I hooked up a Series 1 via Vonage.weese78 said:I was thinking of getting a digital telephone for the house and was wondering if it is good with the series 3. Any problems or reasons that I may not want to get it?
