Mark has trouble watching TWiT netcasts on his iPad. He says the video works on his Mac, but not on his iPad. He's attempting to do this all through iTunes. Leo says it could be that there are versions of the video that aren't compatible with iPad.
He might want to try using InstaCast, instead of Apple's app. Mark could also try downloading different qualities to see if that works.
Meanwhile, Mark says a client of his has trouble with slow Wi-Fi on his iPad. Leo says that Apple has had issues with Wi-Fi on mobile devices. He should make sure they're updated and see if the signal improves without a case.
