Hi all,
Some of you may have read my subtitle problem. In short, when I author a DVD using IFOEDIT, I'm not able to select the subtitles stream I want to play if I play it with PowerDVD.
So, I got that idea: use DVDShrink to strip unwanted audio and subtitles streams (reauthor mode on main movie only, no compression). The IFO files I get would be very similar to the ones I get if I reauthor my audio and video files using IFOEDIT.
I thought that I would just need to use IFOUPDATE to get needed data from IFOEDIT authored IFO files, and import them into my DVDShrink IFO files.
In addition, I had to check the subtitles ratio value and subtitles colors using IFOEDIT.
It worked once already, for the first movie I tried that on. The result could be played fine both on PowerDVD and standalone players. ANd IU could select all of my subtitles streams.
However, this time, using exactly the same method, my resulting IFO files are refused by Nero.
Tests on IFOs obtained from DVDShrhink: subtitles are working 100% fine, as expected.
Tests on IFOs obtained from IFOEDIT: I can't select the subtitles stream in PowerDVD (but it works with the IFOEDIT DVD player).
By real luck, and I don't know how anymore, IFOUPDATE finally gave me a working file (accepted by Nero, and playing subtitles fien in PowerDVD) after some play with IFOUPDATE and IFOEDIT. Everything is fine when playing it on PowerDVD (so I'm about to burn and check on a standalone).
However, if I use IFOEDIT to do a "Get VST sectors" on the main movie IFO, several items get corrected, but the result is refused by Nero (version 6.3).
Yet, right before, as I used IFOUPDATE and its "automatically get VTS sectors", it was already done. So IFOEDIT shouldn't have found something else, I think.
Hence I wonder: is there a difference in the "Get VTS sectors" of IFOEDIT and IFOUPDATE?
Can I trust my working IFO file, since using IFOEDIT and its Get VTS sectors will render the movie unburnable?
As a matter of a fact, I noticed those:
The layerbreak of the original movie will be "compiled" by DVDShrink as a cell without an associated program.
But if I extract celltimes from the original movie, and use them for authoring with IFOEDIT, the layerbreak will be "compiled" as a cell with an associated program.
Hence, I have problems with IFOupdates, and I needed to manually remove the layerbreak in celltimes.txt, so that I have the same number of programs in IFOs from IFOEDIT and DVDShrink. But the resulting authored files do not have the same number of cells.
Hence only "standard method" is working in IFOUPDATE. Anyway, that's the one I needed, according to my first successful attempt on another movie.
That makes a long post... But I'm in quest for explanations on what happens, or more details on how the tools work.
I can also mention that I tried Rejig authoring (latest version, 0.5e I think), and the resulting files are crashing PowerDVD when I try to play them. Rejig produces two VOB file sets (VTS_01_xx and VTS_02_xx), while DVDShrink and IFOEDIT produces only one VOB files set.
I think I have to learn a lot from those attempts, but as I did not manage to get anything working yet, except by luck (and I don't trust the result, since I did not do anything special to get this working IFO file). In addtiotion, IFOEDIT finds thinsg to correct in it, as I said.
This is why I'm looking for help so that I learn what can be learned from those attempts.
Using IFOEDIT to watch at the IFO files, I don't find anything that could cause the problem.
