There have been lots of issues reported lately with viewing the archived UStream recordings. A little research taught me that it is a known issue with UStream, and that most playback issues are caused by bugs in the autoplay ads. To bypass these autoplay ads and enjoy a more pleasant UStream viewing experience, try the following steps:
1. Install the Mozilla Firefox web broswer: FireFox.
2. Install the AdBlock Plus for Firefox add-on: AdBlock Plus.
3. After restarting Firefox, Ad Block Plus will ask you if you'd like to download filters. I responded YES to filters.
4. Enjoy ad-free UStream recordings!
I prefer to use Google Chrome for most of my web browsing, but I have Firefox installed on my computer now. I plan to use it for all my UStream-related activities. I have already tested this fix this morning by viewing the same UStream recording in Chrome and in Firefox. The video played much more smoothly in Firefox, with no ads! There was no starting and stopping in the beginning due to loading issues with going into and coming back back from the autoplay commercials.
If you've been having problems watching UStream recordings, be sure to give this fix a try & let me know if it helps!
P.S. If you STILL have problems after trying that, then it is most likely your version of Adobe Flash Player. The latest release has been very problematic. To download a previous version of Flash Player, go to http://kb2.adobe.com/cps/142/tn_14266.html and download version 10.2.159.1.
P.P.S. And if NONE of those suggestions fix the problem, then you should contact the UStream Helpers at http://www.ustream.tv/help, because I am out of ideas.
