This one does seem to have a decently easy resolution (e-mail them to yourself, or via a cloud sharing service you can access on both PC and iPad).

But I find that in general, Apple devices close themselves off to a ridiculous degree. My wife recently made a short film for a wedding on her Mac... and wow, was it painful getting it exported in a high-quality format. iMovie or whatever it is now wanted of course to export as QuickTime, which for many reasons was not a good option. Now, on my PC, using free software, I can easily export high-quality video in a dozen or more formats. But her Mac severely limited those options without buying QuickTime Pro.
