Nothing fancy about a blu-ray disk as compared to dvd disk that makes being able to read the data tied to the blu-ray disk in terms of storing the data. No they are not the same. I understand. But the data stored is still about digital information and storing that information. While its not totally about storage capacity you don’t need all the storage space of a blu-ray disk to store a blu-ray file. Storing the file and the kind of disk its stored on while not exactly 100% the case, it is sorta apples to oranges. The reason they can store the more data that is needed for the high def file is due to the blu-ray technology being able to hold more data. The data that is the movie itself is not dependent on media. Just like a high def movie can be on hd-dvd or blu-ray, etc. By compression a high def video source you can store it on various media of smaller capacity.
So its not a “blu-ray” movie as in it has to be on a blu-ray disk. Its a high def movie whose file size is huge so to accommodate the uncompressed file size you need a blu-ray or hd-dvd disk. By making the file size smaller you can put it on a dvd. The file is still coded by the blu-ray standards and hence needs the blu-ray firmware to “see” it.
I hope that makes sense. And that is precisely why its not making a dvd from a blu-ray. Its still a blu-ray file. Just smaller.
I guess the other way to look at it is from your hard drive. When you rip to and playback the blu-ray file from your hard drive is your hard drive suddenly now a “blu-ray hard drive”? No, its still the same old hard drive. Its just storage space as is the dvd.[/QUOTE]
OK, that makes sense, thank you for explanation.
as for compression I also follow the steps that you mentioned ie.deselecting audio/video tracks not wanted etc. and one of two things happen with out fail, I either get the 401 error or it starts the scan ( which by the way says it is going to take 3 hrs.) then freezes, I will keep playing with it just so I can do it, but as I mentioned in my last post I will stick with BD disc’s I love the clarity of the A/V, on a all HDMI 5.1 system it just rocks.
