I was still astonished when this "DVD", seemed to have 61 GB of files ! ... anyone come across this kind of thing and why does it exist ? This has to do with the way DVD-Video is "authored", the format's specification is quite complicated[1], so without going too deep; the DVD "filesystem" is just one view of the content—since video, audio, subtitle and navigation streams are _multiplexed_ and stored in the VOB container, you can have multiple titles with their own set of VOB files that reference the same MPEG input streams in different ways, this could be due to multi-angle feature (e.g. for internationalisation, directors cuts, etc) and/or other extra features.
Thanks for that Joel it goes some way to explaining the ; variable success of concatenating the relevant .vob files. However my question concerned the underlying hardware. which seems to normally limit content size to about 4 - 6GB see for example : http://www.osta.org/technology/dvdqa/dvdqa6.htm Where as this video, without any particular notification on the packet, has verified (ie not just file size corruption) content ; of approx 61GB ! regards Rohan McLeod
