@Pardus That looks like a good solution for those on a slow connection, or who pay for bandwidth. I did not realise that audio-only streams were available.
At one point, Vivaldi used to overheat my CPU and cause a hard reboot if I was playing high-resolution video (1024p), which is full resolution on my 1920x1280 landscape monitor. I solved that by setting my default to 480p.
For most videos the lower quality hardly matters. Now, I can play at full resolution without issues, but I just use the lower setting to save electricity and the planet. If I want to watch a nature program like Cheetahs I temporarily switch the quality up to 1024p.
