This is because the html5 player will load the video by default. I have noticed lately that some channels required flash player. Do you have an example video by chance for further investigation?

For those videos that do need Flash well you need the old Flash 11.1 plugin as Adobe stopped supporting Android and BB PlayBook as that version.
