Sure, but I was replying specifically to a post that was directly critical of "most" of the information already posted, without providing any reasons why - just speaking for myself, because I post replies not just for the OP in most threads, but for anyone else who's just googling for info and advice and will read this in the future, if something I've posted publicly would lead someone to approach selling DVDs here in a way that's not of greatest benefit to them, I think it would be more constructive for that info to be corrected or countered publicly so that everyone can benefit from broader or more informed ideas. I don't really understand the benefit of publicly but vaguely decrying info, but keeping private the info that will potentially help more. 

If the OP gets better assistance privately, great, but also just means my understanding of the best way to approach it (potentially) remains flawed and I'd prefer it not to be, if there is a better way.
