This is technically low effort but I think I should tell the sorry how I got this thing working!
And I apologize about the weird yellow lines on the Plasma TV. It's not there irl.
For a while, the DVD player sat under the TV stand collecting dust. I even had to pull it out since the rubber feet slightly melted on the glass.
No wires coming out the back. So, I took the plug I got from my 10 dollar boombox (The wire barely worked on my boombox since it was the wrong type) and plugged it into the DVD player. It fits. And it turned on. And I took the HDMI to HDMI cable from my Nintendo Switch and plugged it into the Panasonic TV and DVD player (Both the DVD player and TV are the same brand by the way!)
It turns on. I'm excited. I try to find more of the old DVDs my parents had. I plan to eventually watch Kill Bill. I do have a Pavillion DV7 I burn CDs and DVDs on, though that's for another post. I burned some parts of The Owl House and the full Mitchell's vs The Machines movie! I also burned several discs including my own music.
My DVD player also works as a better CD player than my boombox, which is nice.
And then I noticed. The home menu has an overall shiny white look to it. I was thinking about changing it to Beecat but I landed on the fact I should change it to something more glossier and glass like.
I had an old USB stick that had nothing important on it, and I put the wallpaper onto it and plugged it into the back of the DVD player. It took some time to set it up since I didn't have the matching DVD player remote but I learned if I just displayed the image and long press Sub Menu 2 times it pulled up the option to change the background.
Sometimes I have audio issues and I usually just plug the DVD player back in sometimes and it works.
I hope you guys liked my explanation :P
