Let's drop this one like a stone, shall we? KarinL

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

Some players are very finicky. I had to experiment with brands and format (R+, R-, RW+, RW-) before finding a surefire disk for my Toshiba player (several years old). Verbatim DVD-Rs for me, exclusively.

Yes streaming apps is not their focus. On the 203 they included a 4k HDMI input so you can stream your Roku/Apple TV, Firestick etc through the player and not lose an HDMI input on your TV. The used to have the 103 and 105 priced similarly when they came out with these blu-ray players. If you assume a 2017 version of a similar feature upgrade from the 203 to the 205, then they are probably something like this: https://www.oppodigital.com/KnowledgeBase.aspx?KBID=37&ProdID=BDP-93 In the 103 /105 case, the higher end version was based mostly on improving the audio listening experience.
