Unable to play videos on LÖVE

It's a general problem, they won't play in example_test.love (I assume you all know what that is) and in most projects (made by other people) they either don't play at all (like in example_test.love) or play REALLY bugged
I don't know if this is a hardware problem or not, but here's my dxdiag just in case:

You're probably missing codecs these videos use.

It's the difference between png and jpg images; it's the difference between lua and c code (kinda); it's the difference between mp3 and ogg.
Codecs or coders and decoders are libraries that enable programs to understand/parse files, and make them into a form "fit for human consumption"
, or in other words, codecs are needed to make files work, in general.
Different files need different codecs, and there are tons of them; most you won't find on your system by default, nor can you get through windows update...
That said, it might still be an issue with you using an HP laptop, but if it's a codec issue, maybe installing one of the packs might work for you (Like the
Combined Community Codec Pack... or download VLC, that has tons of codecs, though i'm not sure if those are available for other programs to use, or not.

To decode a specific file coding you need a matching decoder. Obviously. And your system doesn't have one, so a file cannot be decoded. You need to install appropriate video codecs.

I downloaded and installed CCCP and there's no change, I also already had VLC installed
Also, if it was actually the codecs, wouldn't LÖVE have them either built-in or have them installed when you install the environment?

Why would it? Users can use any type of video in the game, and codecs are countless. So it is game's responsibility to provide necessary software to play back it's own content.

love.video uses the Ogg Theora format for video playback. love comes bundled with the necessary libraries for decoding Theora videos.
When you say they play 'really bugged', what does it look like (does a screenshot accurately show what it looks like)?

Thanks for clearing that up; and I can't quite show you a screenshot because it's, well, a video. I'll try to make you a .gif
Anyway; it looks like a compressed 128p video, the sound is not only laggy but cut off; and the video sort of finishes before time while the sound keeps playing.

What's your CPU usage like (via the Task Manager or similar) while playing the video? What's the resolution and requested framerate (the frame rate that the video is supposed to be playing back at)? It sounds like the video and audio decoding might be doing too much work for your CPU to handle.
