Karl has said in the past that the reason you haven't seen Footwear Repairs come out on any other format than VHS is because TVT still owns the rights to it. TVT was apparently sold to another company in 2008 and i doubt that re-releasing the material on DVD/BluRay is high on the list of things to do
That said, all the stuff post-1998 should still be owned by someone who is _not_ TVT and therefore perhaps there is a chance for some of it coming out on not-VHS and not-YouTube.
