Q??
When i save this avs file and used VD Mod open the file will appear this word!!
(Plugin C:\PROGRA~1\Gabest\Vobsub\text.vdf is not an AviSynth 2.5 plugin.)
Why i need used this filter(textsub.vdf),because if i didn"t used textsub.vdf.....when i preview a anime.The word font isn't i need,but when i didn't used VD Mod open avs file,only used open a anime's raw and append a sub file,it didn't had this problem(Means i see that fonts is i needed)

textsub.vdf is an AviSynth v2.0x plugin. Just use the textsub contained in vsfilter.dll:


LoadPlugin("C:\PROGRA~1\GORDIA~1\mpeg2dec3.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\decomb.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\VSFilter.dll")

avisource("XXXXXXX.avi")
textsub("xxxxxxxxxxxxxxxxxxx.ssa")
