I have no problems viewing any threads. However if you have a newer PC with Windows 8 IE Explorer crashes, freezes, lags and basically PO's user's with many other conflicts. I'm surprised you haven't got the green screen yet, if you have there is a fix.
Try using Firefox, if you already are update it. Right click on the video and click on setting, uncheck the hardware acceleration box, this will cure a lot of problems with videos.
Slow internet connections, slow modems or routers and slow PC's will also cause problems when loading pages.
It's also a good idea to clean junk from the memory, Glary Utilities is a great free one that offers a paid version for a few dollars. I have used it for years along with the factory options and anti virus. I use Kaspersky, it also fixes vulnerabilities, cleans junk files and removes personal data.
I can understand in other threads, but in the music section it's inevitable to end up with a lot of videos in one post.
