I don't have your TV but I found that if I just used a splitter to split the cable coming from the wall and ran one into my receiver and then back out to the TV via HDMI and the second straight to the coaxial input on the back of my TV, I received all channels (both analog and digital for both pictures). Time Warner swore I would need a second standard def cable box but that wasn't true. Also, on my TV, the second picture only displays in 480P but I do get digital channels. Is it possible that the second picture is only picking up stations over the air from the TV's own antenna? I know on mine, that would be a possibility.
I purchased a Samsung LN-T4671 HDTV a few months ago. When viewing the Picture in Picture, I noticed that it will not display the Digital channels that I can get over local air broadcasts. The Picture in Picture will only display the analog channels. My fear is that in 2009 when all broadcasting goes digital, this will render my Picture in Picutre function useless. I called Samsung support about this issue and the person that I talked to said that it should work fine with the digital conversion, that there should not be any issues. This does not seem correct to me, since it currently will not work, even though I have an HD capable antenna hooked up to the coax port.
Is the Picture in Picture not going through the Digital decoder (ATSC)?
How can I get a digital signal in the PIP window?
