HI, This could be an interesting article, particularly for readers who have chosen a single format player namely dvd-a or perhaps a combi. This issue was experienced by myself and also mentioned by a HT installer and ISF'r. A couple of dvd-a producers such as DTS abd HI put all available formats on the opening page of their DVD-a's so access to the dd5.1 or dts track is easily done, you just scroll down to the desired format. However most do not. If you ave both a dvd-a and an sacd player with an optical or coax connection access to those tracks is no proplem as you simply put the dvd-a in the sacd player and it immediately defaults to dd5.1 or dts screen because it does not play dvd-a. Howerver many dvd-a players (whether you go to groups or scroll through audio will not give you access to these formats. Panasonic and JVC are just 2 such manufacturers. It would be interesting to find out which do and which don't so a poll might be in order. When I've posted this elsewhere I've recieved the comment "If you have the best why would you want to access those formats" My response is because I paid for the entire disc and want access to all formats without having to buy a second machine. If you feel that this is an interesting enough subject (which exposes a limitation of many dvd-a machines) I'd love to see an article on it. regards, Peter m.
