each time I perform a new planar map and send them to the uv editor I get a new set of uv's and lose, or can no longer see the old uvs. This doesn't seem to happen to the Kurt in his videos.

I have lots of hours of uv mapping that I have downloaded from the site but none of them have any explanation of the tools used in the uv editor. None of them explain the options in the different option boxes that come with the uv editor. This is very frustrating for the beginning student since the artist is only performing operations without any explanations for the reason one method is chosen over any other.

Frustrated learner ...... looking for explanations about why things are done. Kinda of like watching Michael-Angelo paint, but never learning how he mixes his colors or understanding his reasons for certain color combinations.
