That particular argument was directed at the arbitrary choice of "2 revisions back." Why such an arbitrary number and how would that actually be different than it is now? As for other A/V equipment .. I do believe that Cable boxes are updated in much the same way as DIRECTV's equipment .. except, in some cases there's not even a way to tell that it's been updated. Clearly you liked the previous revision better than this one and also clearly you want to go back to that revision .. Looking at it from a DIRECTV's side and trying to successfully support so many revisions I can understand why they don't do it.
