Okay. This problem didn't occur until I downloaded the Hyadain-My First Friend beatmap. I tried it out, and at first the video was just black. I brushed it off as nothing, thought it was no big deal, and beat it. I tried playing it again, thinking I could do better, and osu starts cracking up! A few seconds later, the whole computer crashes and burns. Then, I decided to play Al-Azif's "Rin Kagamine-Kokoro" beatmap (one of my favorites) and the video stopped working, a message popping up at the bottom saying that I should check my codecs. I reinstall the codec I used to read Div3 videos, and it works just fine. THEN I try out "3rd Coast-Bye Bye Love" and all of a sudden, the video won't work! Others have been affected, including "Lullaby for You", "Hatsune Miku-stargazer", "Horny '98", "Home Made Kazoku-Thank You!!!" (Though that might be because it's an mpg file), and "Ultimate Showdown of Ultimate Destiny" but now, every time I close out of Osu! I get an error message! The weird thing is that these are all avi files, and there's never been a problem until recently. And I can play the files just fine straight from the song's file, but not within osu! HELP!!!
