Muxman failed to mux my SUP/SST

[Anime]

before posting this problem i have already tried muxing my DVD more than 20 times with muxman with alot of alternative solution
I have 2 DVD
I'm trying to bring my subtitle from 1 DVD to another DVD
reason the subtitless DVD is higher quality.

I wish to keep the subtitle & DVD quality intact
the DVD is 24mins+
my .SUP is 1.25mb / if vobsub .sub is 1.66mb

Muxman reported underflow twice if i mux it with my sup.
Muxman can mux back the DVD if i cut my idx->sup to 1st 12mins only(50% SUP)
Muxman can accept 100% of my .SUP or .idx->sup if i process it once with subtitlecreator
result .sup becomes 909kb adding some dirty pixel(SC bug) once it process (so this out.....)

I did tried converting subtitlecreator processed/or not.idx -> sst, muxman failed to mux again

so i'm thinking is there a timing problem in my idx/sup/sst
which makes muxman refuse to mux at the 2nd half of my subtitle(12min~24min)

but by the way ifoedit can freely mux 100% of the sup properbly, but i wanted a work around with muxman because of CLI.... =/

although now i already know to work around this DVD without muxman but i will like to find out why muxman behaves this way...
can someone help? or explain the possible problem timing to cause muxman weird behaviour?

As you are experiencing, the applications used to extract/manipulate your subs play a relevant role in achieving good results...

Did you try to simply use PgcDemux to extract the subs form the wanted PGC of your original DVD and authoring them directly with MuxMan in order to produce the new DVD ?

Look in the log of the failed mux for "SubPicture stream n backwards move in time", "n" will be a number. If this occured all the subs following the backward move in time get muxed into one point in time. This can be caused by the source having more than one Vob. PgcDemux corrects for this.

but i did use pgcdemux thru cli to demux the dvd
PgcDemux.exe -pgc 1 -m2v ...

and this is the only "demuxed" muxman refuse to mux for me....

giving the vob and 0kb ifo without bup
and complaints that the dvd will not works proberly in the log.

even after i mux with ifoedit then voblanker, then pgcdemux the sup+source again from the new working dvd, muxman still refuse...

all along i been using pgcdemux cli to demux
then follow by muxman cli to mux
then follow by vobblanker cli to replace

thanks for reply^^
