Any person interested in understanding or modifying the operation of a DVD will be interested in PgcEdit as an excellent freeware program which makes it possible to modify almost all of the information contained in DVD IFO files. PgcEdit offers an easy to understand view of a DVD’s programming. It allows you to edit, via easy to use GUIs, all the DVD’s commands with their legal values, without any limitations except those imposed by the DVD standard.
PgcEdit also has an extremely powerful but easy to use PGC Editor, where you can make changes to stream assignments, subtitle colors, the chapter table, cell and PGC still times, the cell flags, VOB/Cell IDs and many others, again through an easy and intuitive GUI.PgcEdit is also a basic DVD authoring tool – by using its new DVD command, combined with importing menus and titles and its Command Editor, you can author your DVD from scratch. The main drawback is that it takes some time to familiarise yourself with DVD structures but for professional or amateur filmakers, this is an excellent tool.
