When playing 4:3 YouTube videos on the Classic CRT, the video gets squished. There is a workaround to this, but I’d prefer it if the player would properly play them.
For those who are interested, there are 2 workarounds:
1.) Use a Theatre Screen and plaster it onto the CRT, however, it will stick out from the sides.
2.) Rip the video, stretch it in a video editing software, and reupload it. By reuploading the video, you risk getting your channel removed if it violates copyright law (9/10 times, it will).
Both workarounds have their positives, but they also have major negatives.
