content: This model TiVo is out of date. It will only record Digital and Analog programs and NOT Hi Def. You must have a Multi-Channel tuner card installed in order to receive cable TV channels -- this costs $1.50/month plus a $20.00 installation charge from Comcast -- plus the monthly charge from TiVo is $12.95 (as I recall) -- this is an EXPENSIVE proposition.I'm returning the TiVo because Comcast offers their Hi Def DVR for $9.95 for 6 moths, then $12.95 there after.Oh did I mention that if you have Vonage or cable telephone service that you MUST buy a wireless adapter for ~$50.00?This is not only an outdated piece of equipment, but a very expensive solution to recording TV programs/movies!
