Different recording on computer that what was recorded

A few times I have recorded a basketball game on the DVR and tried to watch it on my laptop or tablet but it ends up showing a recording of a different channel that the one I programmed. If I go to watch it on the TV it shows the correct program that I recorded, what's up with that? I try to watch it on my computer so my wife can watch the TV as she isn't into basketball. It is really frustrating and definitley confusing. Anyone have this problem or a fix?
