Sorry for my stupidity

(seriously).
I have a little experience meanwhile but not so much with manual KVCD procedure (That's what lead me to DVD2SVCD in the first place).
Subs was the problem for me in the very beginning and now again. I haven't been able to find a good guide for subs.
But, I think I can make a new .avs script with note pad using the Textsub command yes ? Something like:
Mpeg2source("D:\Scarface.d2v")
BlindPP(cpu=4)
Blockbuster(method="noise",detail_min=1,detail_max =3,variance=0.1,seed=1)
Convolution3D(1, 6, 12, 6, 8, 2.8, 0)
GripCrop(352,288,overscan=1, source_anamorphic=false)
GripSize(resizer="LanczosResize")
Undot()
TemporalSoften(2,7,7,3,2)
DCTFilter(1,1,1,1,1,1,0.5,0)
GripBorders()
Textsub ("d:\scarface.srt")
Will the quality be affected by the re-encode ?
Is the syntax for "textsub" correct ?
Can I use the .style file for subs and how do I preview the position of the subs ?
Sorry to keep on bugging you...
PS: by the way, my Pinokkio project (2 SVCD discs -> 1 KVCD dis) turned out fantastic ! Thanks for your help on that. I'm getting the hang of it
