Locking PiP Questions?

Dear Cox;

For 2 years your subscribers have asked why, when they "upgrade" their cable boxes, they lose Picture in Picture?

It's a fair question--and it just happened to me.  No one told me I would lose it...they just gave me a "better" (Cisco) box.

2 years ago, you said "it will be a forthcoming firmware upgrade" -- now, you say "it's for the TV" -- which is nonsense.

Finally, on all the forums that ask it, you have locked them down.

Why?
