Technology Challenged

We think Audrie did something to a setting on the TV that made the TIVO not work.  At first we thought the TIVO had died, but when we hooked it up to the other TV it worked.  So with much bruhaha we managed to get the TIVO back working.  Afterall the new season is upon us.
And that's when it happened.  We got a call from Comcast to let us know they were switching to all digital and our TV would not work anymore without an adapter.  So the little man and I spent an hour at the Comcast center getting an adapter and a cablecoder for the TIVO.
My TIVO is before cablecoder technology.  I went online and found I need a black cable box otherwise if I use the adapter I will lose my dual tuner ability.  It would be like going back to VHS and only being able to tape one show at a time.  Ha.
So the little man and I again traipsed to the Comcast center.  And even though they were busier it didn't take as long.  Turns out the lady had to get a tech who then informed her that I would need an OLD box to work with my TIVO.  She looked and she looked.  Came back out and told me I had no choice but to have a tech come out to the house and install the box because they did not have any.  Okay.  I asked about charges and yes there is a charge for them to come out and they would need to know about needing the old box before they came.
I make the comment that perhaps my best bet is to just buy a new TIVO. The woman looks at me and says why not just get their DVR. I look right back at her and say no.  I have basic limited cable and that isn't usable with their DVR.  You must have a good package and that costs $65 a month which is a lot more than $17 a month, plus the cost for the DVR.  No thanks.
So I took my cablecoder back and the little man and I went to  Best Buy and bought a new TIVO that will work with the cablecoder.  Now we just have to hook it up and see if we can make it work.  Afterall the new season is upon us, you know.
