Setting First Play with IFO Edit(or anything else)

[Seph29]

What I'm trying to do is set the what should play first when the DVD is inserted. Normally this is already set and it's just a matter of editing the proper "Pre" Command in the PCG command table in order to change it. However, this DVD has no First Play defined therefore there is no Pre value to change.

In this case there is no Pre command because a first play was never defined. This can cause problems when playing back on certain devices and players. I was wondering how I would go about setting the first play without having to reauthor the DVD.

So far I've tried right clicking the PGC command table and selecting "Add PreCommand". This will seemingly create all of the necessary tables and then I can go back and edit what the first PreCommand should be. I've also noticed that it adds 3 other huge tables, namely the PGC program map, cell playback info, and cell position info table. I don't usually see this in most DVDs I've opened up w/IFOEdit, but I assumed it was still ok. However, when I choose to save the IFO file I get an error similar to the following: "There's something wrong! The IFO End sector does not match the filesize." After this I'll go to check my VIDEO_TS.ifo files and they'll be only 2 kb when they should be 12. Anybody know a way to accomplish this that actually works, or perhaps a way to fix the error message I'm receiving? TIA.

Try saving your IFO and BUP and pressing your "Get VTS Sectors" button.

Already have, but it doesn't fix anything. The file it creates when I first save is completely unusable. If I open it up in IFOEdit it doesn't contain any tables or anything, if I try to play back in a Software player it won't do anything.

My first instinct was that the problem had something to do with the extra tables it added, but I'm not really an expert on this stuff so I'm not sure. I have no idea how to go about fixing it either.

Did you rip all your files? What files do you have?

Hmm.. guess I should further clearify what this is exactly, what I'm trying to do and why I'm trying to do it.

This is a home authored movie, not professionally mastered or something like that. When the movie was authored it seems the author neglected setting a "First Play" item(Perhaps he used DVDMaestro which doesn't set one automatically??). Normally this is ok since most DVD Players and such will automatically assume you want to play titleset 1(there is no menu), but some players(more specifically PowerDVD in this case) require you to set this or it will refuse to play them back. I wanted to issue a "fix" for this issue so that people could play it back in their set top boxes or in PowerDVD without worrying about any problems.

Hopefully this illustrates better for you what the issue is.

If you already have files like

VTS_01_1.VOB
VTS_01_2.VOB
VTS_01_3.VOB
.

VTS_01_*.VOB

You can create new IFOs in IFOedit. Here's the guide (http://mpucoder.kewlhair.com/Derrow/createifo.html). You'll get a Jump to Title 1 in your First Play PGC. This is for movie-only backups.
