What do you think HD-DVD will be stored as? I know that it can be 1080i (50Hz) or 1080p (25Hz), just as SD-DVD can be interlaced or progressive, yet all DVDs are interlaced. The advantage of interlaced is that all TVs will be able to display it without work from the player, yet some players can deinterlace it and output it as 50Hz progressive to compatible displays. (Not many HDTVs will be able to display or accept 1080p at first, just as not many TVs were progressive when DVD came out.) If it were stored as progressive 25Hz the player would have to interlace it for non-progressive sets or double to frequency to 50Hz for progressive sets. Now this seems like more work to me and added expense. On the other hand as every player would have to do this, there would be no such think as 'expensive progressive players', a bonus for us who would want that. (But not so good for the manufacturers trying to rip us off!) I would like to know your views on this.
