I couldn't find much info on Toshiba's site regarding the Picture in Picture features on this set or any others. Will it support split-screen PiP? Like one full cable channel image on the left and one full cable channel image on the right? Or am i stuck with the little tiny box to have my PiP in? Can you select difference sources for each PiP input? Like digital cable box for one and TV tuner for the other? Thanks for any info you can provide on this subject! Jason PS - anyone know of any good sites with a more comprehensive list of features and functions or where i can find a user manual for this TV or a similar one?
