One problem that I just found with my system Win 7 32bit, IE9, and Youtube is that if I go to Youtube and click on a music video to play to listen to the music, and then minimize the window or switch to another web page by use of another browser window or tab to open a new window. The video stops after a few seconds as if the session is lost to youtube. I go back to the youtube page and I have a cartwheel at center of video window and the play bar shows that about 1/20th of the content streamed or loaded to the play window and STOPPED at say 35 seconds into it. If I keep youtube maximized (and) keep the ad active at the bottom of the video window, the music video plays without any problems. However if I have the screen maximized and kill the ad with the [X] in the upper right of the ad, the loading stops and the video will only play to that point.

I am thinking that either I have a problem with that site, or they dont want me to play the music video if I am not watching their website and its advertising. Anyone else experience this? Or any suggestions on what to check out on my system if its not youtube?Strange...
Ran a test on connection speed lately ? ?Hello Patio

Yes, ran speedtest on it to test upload/download and I have 20mbps download and 12mbps upload with Comcast broadband, measured against a near by location in Manchester, NH. Downloading content download fast and watching shows on hulu and crackle run with no problems.

Its too bad I cant share an avi of the symptoms to show you the nature of it. CamStudio is perfect for recording and showing this type of problem, but a quick avi video would be like 35mb or so in size.

Also to note that this issue is experienced all hours of day including like 4am EST when there should be little internet conjestion in the USA with most people sleeping from here in New Hampshire to California.Good enough...
That would make my next suspect the browser ...
Run it with all addons disabled.....if still the same try Firefox and see.

Hey good idea! I will give that a try tonight when I get home from work. ThxWell I tried Firefox and same exact problem as IE9. Attached screenshot of it. You can see the cartwheel at center of video as it stopped and is cartwheeling, but NEVER picks up where it LEFT off. If you move the radio button to move it FORWARD a second or so, it will play the next minute or so of the video or sometimes the whole rest of video.

Last night, I checked my bandwidth with http://www.speedtest.net/ and had 20mbps down and 4mbps up.

I also checked into if Comcast was shaping my bandwidth based on content type and it came up with no detection:
