Need PIP help
 

Any suggestions on configuring PIP?
Here's my setup
50" HD ready toshiba rptv has colorstream inputs as well as the usual coax and s-video
Comcast HD cable box
Can I use a line splitter and run one split to the box and one to the TV/ Or do I split the signal after the cable box?

It sounds like you want to split your cable feed. Does your cable require a box to tune the channels or does it work directly?

You will need to split the signal before it goes into the cable box. If the regular tv tuner is sufficient, then one can go into the cable box and the other into the tv.
