I have several computers set up on a network. From time to time, they will not play youtube videos. Sometimes one will play but not the other, sometimes one will play a certain title but not another. I can even have one video playing in one browser window and one failing in another on the same machine.
I can take the url of a video that doesn't play on my machines and play it on my phone, so the video link is ok.
I've done my google/experts-exchange research and eliminated all the usual suspects, which include:
1. cache/cookies/java/flash versions
2. disk space
4. system performance in general - happens on multiple systems all Windows. Most are windows 7 but it happens on XP as well
5. network performance - I can stream vimeo videos all day long no problem. checked and verified bandwidth.
One video I can never play is the "speed test" video in youtube. I can be playing a youtube video fine in one window, but in the window next to it the speed test video says "an error occurred. Please try again later".
Today no videos were playing on any machine. I started trying to diagnose it and with no apparent change, after about an hour, some videos started playing.
I'd offer 1000 points to get this fixed, but can only offer 500.
