IfoEdit bug with video aspect ratio and subpicture IDs

[r0lZ]

I have a problem after authoring a 16:9 video with two soundtracks and two subpictures streams. The muxing with IfoEdit is OK. The subpictures streams are ID 0x20 and 0x21, which is perfect. But the film has the wrong aspect ratio 4:3.
To change the aspect ratio to 16:9, I use the VTS Overview/Title Set attributes/Video attributes dialog.
And the second subpic stream ID change to 0x20! :confused: (You need to refresh the IfoEdit's display to notice the fact, but that's a fact)
I end up with two different subpic languages, both sharing the same ID, and showing the same subtitles when playing: the first language.

My guess is that it is an IfoEdit bug, and that you can't change an aspect ratio from 4:3 to 16:9 without messing us the subpictures IDs.
I tried changing another IFO from 16:9 to 4:3, and then back to 16:9. This work well! Strange.

Somebody know about this problem? Is it a workaround? Any safer way to change the aspect ratio?

Thanks...

Just a thought -
Did you forget to change the VIDEO_TS.IFO aspect ?

No. I have also changed the Aspect Ratio in VIDEO_TS.IFO. In that file, there is apparently no problem, but the substream IDs are not visible here.
After changing the AR in VTS_01_0.IFO, the video play at 16:9, regardless of the setting in VIDEO_TS.IFO. The problem is not in the AR, but in the streams IDs after changing the AR.
