how to modify/edit an IFO file ? Help

[emistral]

I have backuped a couple of my DVDs using always the same method of reencoding and I have always the same problem (the dvd works on the computer but not on the standalone player). I use CCE then author the DVD with IFOedit.
If I use Rempeg it works fine.
However when authoring the DVD, ifoedit only generate an ifo file which has no menu table and only one PGC and therefore I can not use the _0.VOB file from the original dvd. (getting warning when I do a get vts sector and the movie starts straight away when loaded on the computer)

The original IFO file has all the menu tables but has several PGC. The movie is in PGC-1.

so on on side I have a generated IFO file with no menu table and only one PGC which will work fine on a standalone player but I lose all the menus and on the other side I have the original IFO file with the menu tables and 3 PGC and this does not work in the standalone player since 3 PGC are specified but I have reencode only the movie which is in PGC-1 so I guess the standalone player is confused.

so my question would be: how can I transfer the menu tables and other menu information from the original IFO file into the new generated IFO file so that I can use the menus (_0.VOB) in my backup ???

I tried with Ifoedit but I can not figure out the way to do it

also what will happen if after reauthoring with ifoedit using CCE files, I load the celltimes.txt file from the original ifo file (see ifoedit authoring guide) ?

Since chapters are expressed in frames, after reencoding with CCE, the number of frames should be different shouldn't it ? and therefore the chapter list screwed up ?
will this have an impact on how the standalone player starts to play the movie or only the chapters will mismatch ?

Thanks and happy new year to all of you

There are plenty of tutorials for what u want.

PS: Personaly I recommend DVD2DVD-R to do what your backups, it ROX!! (you will still need ifoedit but these steps are verrry easy.)

Thanks Neoh.
could you tell me where to find these guides or tutorial because I have looked everywhere (vcd help, doom9 guides) and I could not find any information on how to transfer menu tables into different ifo files or even how to edit an ifo file.

I have used all the guides I could find for backing up DVD.
When using Rempeg, I had no problem while remuxing m2v files. but as everybody knows the quality is ok as long as you don't decrease to much the bitrate. So movie are so big that even keeping only the movie you need to drastically decrease the bitrate and if you use rempeg, the quality is crap.
So that's why I swap to CCE but unfortunately CCE is not compatible with ifoedit when remuxing
so all my problems appeared when I started to use CCE and reauthoring the movie.
As I said I want to reauthor the dvd only for the vob file for the main movie
Then I reintroduce the new generated vob files but I kept the original ifo file in the dvd structure to access the menus.But at this stage everything seems messy because the generated vob file has one PGC while the ifo is describing it with 3.
adn I guess this in the problem which prevent the DVD to be played on a standalone player although it works fine on a computer
