Ha! What do you know. Just tried it with one of the LR4 zips on an iPad 3 and it worked fine. The file downloads, then you are prompted to open in goodreader. Once you do, you tap the file again in goodreader and it unzips and all the .mov files appear. The movies are listed in the goodreader app but are not appearing in the videos app. You just tap them to play. Cool!
