For those that are interested the new version 9 of PgcEdit (the free DVD IFO and Menu editing program) has finally been released.
This version has been under development for a year now and the program has been upgraded with a massive number of improvements and enhancements.
IMO it was already the best DVD structure editing program available and the new version has already won the author an award.
Some of the new highlights include a full preview with audio and a one click option to remove all irrelevant material from the DVD thereby simplifying its structure (uncalled PGCs, useless cells, useless commands, uncalled titlesets, links to void PGCs, useless menu VOBs etc).
It's free software so if you're interested in this type of thing check it out as it's very highly recommended.
Full details available from the PgcEdit home page and if you're wanting to check out the changes the 'What's New' page is available here.
