Yes! I found the solution. This is on another forum, I don't remember the URL already, but I copied the text, and send it below:
----
The problem is solved if we set to "1" the flag in the right position.
The positions are 4: 4/3, wide, letterbox, pan&scan.
Normally only the middle 2 parameters are set to 1: wide and letterbox.
If we remux a M2V originally in 16:9 with a M2V in 4:3, we can't see any subtitle, eccept
for the first one (0x20)
Well, now I set to "1" ALL the 4 parameters, but there is still another problem:
how I can be able to obtain the right decimal value?
It's more simple than it appear.
Look at PGCITI, in the row "subpicture stream status".
There is a GREAT negative decimal value.
At extreme right there is the analogue value, in hexadecimal format.
Look a it:
if is on stream 1 (0x20) the value is 80000000. Better view in 80.00.00.00
if is on stream 2 (0x21) the value is 80010101. Better view in 80.01.01.01
if is on stream 3 (0x22) the value is 80020202. Better view in 80.02.02.02
Do you see the redundance?
Yeah!
If we wants to be able to see the subpicture with a movie in 4:3 we must set the first
parameter like other 3.
I'll be more sharp: we must set a value ugual as the stream number.
If the value is ugual as the stream number, we can be able to see this subtitle.
If the value is zero, we cannot see anything.
Yeah, the first stream (0x20) is particular, because even if is set ALL to ZERO, we can
still be able to seen the subtitles in each mode, because the stream is number ZERO!
example:
I wanna to set subpicture stream 2 (0x21) to allow the vision on 4:3 format.
I must change the exadecimal value in 81.00.00.00 (stream 1, value 0, stream 2, value 1... stream 3 value 2... etc)
In this case, I purpose the modify of all parameters ON
The 81.00.00.00 will be 81.01.01.01
What is the analogue decimal value for 81010101?
Open your f***ing calc.exe, switch to scientific mode, and calcutate it!
I've calculate ALL parameter for first 12 subpicture (I think that is enough!)
Just substitute at the original.
Here is:
stream code 4:3 WD LB PS Hex
1 0x20 -2147483648 0 0 0 0 80000000
2 0x21 -2130640639 1 1 1 1 81010101
3 0x22 -2113797630 2 2 2 2 82020202
4 0x23 -2096954621 3 3 3 3 83030303

12 0x2b -1962210549 11 11 11 11 8b0b0b0b
Now, is all perfectly functionally.
