When you use the Time Warner Digital box, you're using the tuner inside that box rather than the tuner inside your TV to select a channel. Picture in picture TV's have two tuner's inside so you can view two channels, but they can only tune the analog channels from your cable company, and only if it's hooked up in a manner that will permit this to happen.
So you only have one digital tuner (the Time Warner Box) so you can only view one channel at a time even though your TV supports Picture in Picture.
It MAY be possible to have limited use of the PIP if you connect your TV in a different way. Your Time Warner box is most likely connected to your TV set with composite cables, those are the Yellow, Red, White cables. If you buy a coaxial cable splitter and split the cable before it goes into the Time Warner box you can then run a coax cable into both the Time Warner box and the coax input on your TV. This would allow you to tune the analog Time Warner channels with both of your TV's tuners. In my area I think the first 60 channels or so are still available in analog, but there is no way to watch any of the higher premium channels without the Time Warner box.
If you go through these steps and you select the coax input on your TV your PIP will work on the lower channels. It MAY be possible to tell your TV to display the input from the composite cables on one of the PIP screens and the input from the coax on the other, but I kind of doubt it.
I know this sounds complicated and if you're not familiar with the way all this works it is complicated. The reason lots of people won't respond to this kind of question on this site is because there is no easy fix and by trying to help I run the risk of getting a bad rating. I don't get paid for this, I just like trying to help, so if I have not explained this in a way that's helpful to you please ask some additional questions before you give me a bad rating. Thanks.
