MK802: Youtube network issues

My wife and I have started to watch a lot of Youtube shows.  While most episodes are short, others are longer.  CrashCourse episodes are over 10 minutes long.  TableTop episodes are over 1/2 hour long.  We watch the episodes on various devices.  The episodes view fine on my laptop on Google Chrome.  My Google Nexus 7 plays the videos just fine (notice a trend with the vendor?).  The Youtube app on the MK802 is having connectivity issues, though.  The app will download 1 to 2 minutes to the buffer, then it will just stop.  You won't notice it until the video hits that mark.  Then you get the spinning circle forever.  I have found that switching from HD to SD tells the Youtube app to redownload the video, but starting from where the connection was lost.  Then, 1 to 2 minutes later, it happens again.  I switch back to HD and start over.  It is a pain.  This happens with both of my MK802's, so I know it isn't a problem with that particular device.
