Well, I have never tryed the DVD's you have listed. But I have used a few others. and for the money Id go with GT.. I was a "Free member" for some time, but never really used the site much, untill about 3 weeks ago or so When I wanted to learn guitar again and went on and signed up for membership.

The DVD's you have might be good, but can you ask them questions and get real answers like you can here on GT?

I can tell you that for me, I went about a year or more trying to learn guitar from free internet sites, DVD's, books..pretty much gave up due to how boring it became.

Then a few weeks ago I picked up my guitar and wanted to learn how to play it, this time really learn how to play it.
Got myself a member ship here at GT, and have learned more in the past 2 or 3 weeks than I did in a year of free sites, books and DVD's.

Just my 2 cents.
