If you read my first post, you would see that I have been monitoring the site for some time. The problem is that the Wiki, in particular, has much information that is out of date (like "in the forthcoming 710 release" etc) so it is difficult to work out the current position.
I have deliberately split my questions into several posts to keep things focussed. I find that both here and on other forums, people who post a long series of questions usually prompt a discussion about one of them and then the others get lost.
I appreciate that everyone here is voluntary and peer-support is given out of people's goodwill, however simply having a dig at someone helps nobody and anoys many, not just the OP. Somone doing a search for Blu-Ray will now find this post, see 2 responses, expect that some useful information is to be found and be disappointed.
Are you able to help by posting something constructive?
