I don't know why this started happening, but since yesterday when I put a YouTube video in fullscreen in runs fine, then when it's switching to HD it freezes on the image and the sentence it gets stuck on repeats over and over. If I move the mouse and put it into normal window, it resumes playing. I already tried the "disable hardware acceleration" and clearing the cookies from Firefox, but still happens. Last weekend it was working perfectly fine, even when going into automatic HD on fullscreen. I recently updated my Nvidia drivers to 332.21, and I thought it was because of that. But when I reverted them back to the drivers I had from March, 314.22, it still happens. Maybe it's something with my Nvidia control panel? Also, I just installed an update on my Windows 7, called Microsoft .NET Framework 4.5.1 for Windows 7 x64 Systems. Could this have affected it? Thanks in advance!
Just watched a YouTube video from an external site and put it on fullscreen, and it didn't freeze or anything. The site was TheHobbit.com and I watched one of the trailers that plays from YouTube and no problem. So why does this happen on YouTube then?
