Default Chapter Questions

what file determines the breaks in chapters?

for example, yesterday i ripped the manchurian candidate...the ENTIRE disc onto my hard drive. then, using nero recode, i chose the option to burn the main movie to the DVD. when i popped in the main movie, everything worked fine...however, what i noticed was that the chapters were still intact. i could skip ahead and back between chapters...how is this possible when all i burnt to the disc was the main movie? i thought it was the IFO files that included the chapter info...

"i could skip ahead and back between chapters...how is this possible when all i burnt to the disc was the main movie?"

Look at the files on your burned DVD - You'll find the MOVIE's .IFO and .BUP files as well as the .VOBs - all the chapter points are still in tact...

DVD Shrink creates its own (very basic) IFOs, which, yes, include chapter points.

Both Nero Recode/DVD Shrink analyse the DVD and just adapted the the original movie ifo, whilst retaining the chapter information.

Chapters can be created only at the start of a "cell". So, to that extent, they are in the VOBs, as in the absense of IFOs, they can be created by looking at where each cell starts.

Enough wezman?
