oh well you have every type of connection on there you could get and you only need ONE! IF you have an HDMI cable that goes from your TV to the DVR player that is it that is all you need disconnect all those other cables! the HDMI is video and audio all in one cable that is the advanatage of HDMI one cable and the highest quality. The other options are only to be used if you are using devices that do not use HDMI. So plug the HDMI cable to either the DVR or the DVD depending on which one you want to use, then use the the red and white RCA jacks on the tv (it does not matter if there is a yellow one beside it that yellow is for video not audio so you will use the red and white only) plug your headphones red and white male cords in to those red and white female out jacks on the tv. That is all! leave all other cords out of the equation. As long as all of your devices that you want to connect to the tv have HDMI use that. IF your tv did not have HDMI then you would use the 3 colored ones yellow white and red that carries video on yellow and right and left audio on the red and white. Ok try that just the HDMI cable and your head phones. BE sure that the source input on the tv is set to HDMI if that is what you will be plugging the DVR or DVD into, if the source input is not selected on the tv you will not be getting the signal. This statement right here is very baffling -a 3-prong (yellow, red & white) from the TV (video out) to the three middle (audio out) jacks on the DVR. you state you are going from tv out to DVR out you can not go from out to out there has to be an IN for anything to work. But you do not need those cables so remove them completely from the equation. HDMI out from DVR to HDMI cable IN on the tv period. Headphones base unit red and white male plugs into the TV red and white female audio out jacks. Period

You either have to change the input select on the dvd recorder to s-video (and you may find there is a set of audio inputs separate for the s-video) or you may have to enable the s-video output on the laptop - there may be a control panel or something in your settings for that. Your HP handbook should tell you how. Good luck with it.

Thanks for responding, klaa2. I had no luck going from the wall directly to the TV or from the wall to the TV via the cable box using the cable outlet my old TV was hooked to. I ran it to a cable outlet in another room, and now both the cable box and TV are working. The old TV worked fine in that outlet, but I couldn't get the cable box to even register the time and the TV wouldn't pick up any channels (analog or digital) when I went through the setup scan. I'm using coaxial cable from the wall to the cable box and HD composite cable from the cable box to the TV. The cable box didn't come with an HDMI cable, but that would eliminate some cords. Should I get one? If I understand you correctly, after hooking up the HDMI cable, I'd need to set the cable box to output the HDMI signal and set the TV to receive the HDMI signal. Then, I'd need to go through the auto channel scan again, right? I'm not using a cable signal booster, unless the cable company has one installed that I don't know about. Maybe there's a signal booster at the outlet that I'm having problems with and the outlet in the other room (that's working) doesn't have a signal booster. I'm glad to know that the cable box and TV are both in working order, but it's scary having that cable running into another room. I'm kind of a klutz. Thanks for your help!
