The Samsung PIP window will only display a signal from the internal tuner. Therefore, split your Comcast cable before the cablebox, feed one coax into the box and feed the second coax cable into the RF input on the TV. Set the Source to "TV", find Autoprogram in the Setup menu, and scan for cable channels. Comcast is still broadcasting all local channels in HD, and several other channels in SD, all off the coax cable (called in the clear). With the source set to TV, the TV's internal QAM tuner can access those HD channels on the entire screen using the Samsung remote: if NBC in your area is channel 4, press channel 4-1 on the remote to watch NBCHD.
To watch PIP, go back to using your Comcast box by selecting, with Source, the HDMI input it's connected to for the main window. Press Tools on the Samsung remote and turn on PIP. A small PIP window will appear. With the menu you can relocate it and resize it. Use the menu item to select the channel to watch, I believe you have to scroll through the ones you autoprogrammed.
If Comcast ever stops broadcasting local channels in HD, or, if you want the full complement of cable channels (CNN, ESPN, etc.) you could use a cheap second Comcast DTA box connected to the second coax cable and plugged into the RF input. The TV's internal NTSC analog tuner will allow you to view all cable channels in in the PIP window. Since the DTA outputs an analog signal, you'd select channel 3 with the PIP menu then use the DTA remote to change channels.
The PIP window also works off an antenna. With only an amplified indoor antenna, the TV's internal ATSC tuner can pick up local digital and HD broadcast stations within about 25 miles. Connect it to the RF input, scan for "Air" or "Antenna" channels, and display them in the PIP window.
