Great videos. I constantly have buffering issues with these videos. Is there a fix?

Thanks

Dear Renee,

You may want to check your connection speed- a faster speed (measured in mbps, or megabits per second) will decrease buffering time. Ask your IT staff or visit http://www.check-speed.com to check your connection speed yourself. Time of day and congestion amount or high traffic will also be a factor. Try to play the videos when internet traffic is low. You may have to do a bit of experimentation.
