Comcast internet and digital cable

Let's just skip to the punchlines, shall we?

1. You think your order is being understood by the other person in the online chat but they can still totally screw up your order. At the end of your chat, you'll get a chance to save it.. and do so.
   
2. When they hookup internet, they'll use a computer. To hook things up to a router/switch, turn off the cable modem and hook it up to the router. Then turn the cable modem back on, as it remembers the mac address it first sees.
3. Don't rent the cable modem for $3/month. Go online and buy one for $20-$50. When I told the nice tech who came out to install the modem, he was shocked that I had bought mine for $20.... he was renting himself (!)
4. If you have a Tivo HD, you only one CableCARD to get two channels at once.
5. We got all the HD stations in the basic package but two. ESPN2 and TNT. How odd. Turns out these channels are at the highest frequencies (near 800MHz), and many older coax splitters only work upto 600MHz. Who would have thought that!?! Also the internet comes in at a fairly high frequency. The comcast splitters work upto 1030MHz.
6. Turns out our Radio Shack splitter went upto 900MHz so it wasn't the problem. Squirrels were. They had eaten away most of the outer black jacket of the wire from the phone poll to our place causing impedence issues.
