newbie newbie question

After reading a lot on the doom9 guides and in this forum, I have been wondering why is it that you cannot make a player that plays the exact same movie as in a standalone player. I am ofcause refering to that sometimes when you made a copy of your DVD, it can be played on a computer but not in your standalone...

The reason is that standalone players do not use the same file system as PCs. To the standalone player the pointers within the ifo file are all it uses, there is only one large collection of data in place of the many files we see on a PC, and the information MUST be on the disk in precisely the right places. On a PC, especially using a HD, the data is broken into files no larger than 1GB, and they can be anywhere, and even fragmented. But the player should work, so it uses the PC file system, translating pointers into relative offsets of individual files.
Until a player that can play from image files comes along, using ifo pointers as relative pointers within the image, there won't be a sure way to test on a PC.
