I'm dismayed to read that the simple layer change is STILL causing problems on players this many years after DVD hit the market. The DVD adventure seems to be one screw up after another from the original concept of the standard to how its implemented.
I still, to this day, have not heard a believable reason why the widescreen and std version cannot be on the same side, that is, WHY the 4:3 std version is not just a true pan-scan clipping box that selects a portion of the widescreen data for display - the control signal defining where the clipping-box is could easily be hidden in some low bandwidth sub-channel type of thing.
Anyway, back to the actual topic: Layer change lag. When players cannot buffer the change from layers on the same side of a disc, and given the fact that the industry never went with implementing dual-head players that could play double sided discs without flipping them, WHAT sort of mess will we get with multi-disc movies?
I'm thinking specifically of the comming extended version of Lord of the Rings: Fellowship - which has additional 30 minutes of footage. The movie, from all that I am reading, will then be split accross 2 discs. ARGH! I can only 'assume' the disc change will at least be at a scene change and not in the middle of some action, but given how SLOW some of the changers can be in changing discs, I can imagine a 30 second delay in the flow of the film while the disc changes.
I suppose, given that, by some accounts, 95% of films fit on a single dual-layer disc side, there is no commercial reasoning to build a standard dual-headed, single-tray player. Given that the produced discs are apparently going to split films that don't fit on one dual-layer side onto 2 discs, rather than the 2nd side of a 2 sided disc - will there be ANY move to build and sell at least SOME dual-well dvd players that are synchronised to seamlessly jump from disk 1 to disk 2?
I'm allready ****ed at the idea of having to get up out of the chair to put in disk to of the LOTR special edition.
