If you search the iPad forum for: iPhone AND video you will get past posts on this subject. However, there are a lot of pages of post and not all are relevant.
I use the following method with Goodreader (99 cents):
1) Move video from iphone to the computer (I have windows, so it's drag/drop on the desktop.)
2) Hook up ipad to computer.
3) Drag video file to the Goodreader file import area in itunes on the apps tab.
4) sync. THe video is now available for play in the Goodreader library.
Also, for publishing the video for family, I use dropbox to generate and email them a link. Dropbox can also be used for moving the video files to multiple pc/devices. It is free for the first 2 gigs.
Red555 helped me earlier. I think this post is what you're referring to. There is 1 checkbox to transfer your new movies that you MAKE on your iPhone to your iPad. And yes they play in the iPad's Photo App.
