Yes, the cable company would be happy to rent us converter boxes if we would switch to digital. But that would prevent the DVRs from choosing which channel to record. The E100H doesn't have any means to control what channel a cable box is tuned to.
Basically, the DVRs record everything for the week unattended, and we watch programs when convenient, usually weeks behind when it was recorded. (We catch up in the summer when it is too hot to go outside.)
$27 for basic cable, $34 to include the "non-broadcast" channels (no premium), and $41 for Internet (8M).
Researching TiVo further, I see they now have a means to transfer recorded programs over to the PC, where they can be written to DVD. However, that is $500 + $500 for the fee, and I would have to run more Ethernet links into outside walls.
