I think this is still true for vsrip, pass the file name to the exe in command line.
vsfilter is for virtualdub and avisynth (all versions and all colorsapces), and also has dvobsub in it (can be regsitered with regsvr32.exe).
# usage: rundll32 vobsub.dll,Configure <paramfile>
#
# inputpath\vts_01_0.ifo (inputpath\vts_01_*.vob exist)
# outputpath\onlythefiletitlehere (outputpath can be the same as the inputpath)
# 1 .. n
# - selects the program chain (set the same pgc you did at the dvd ripper program)
# 0, 1 .. 9 + v1c1 .. v99c99
# - 0: indexes everything (not recommended for multi-angle dvds)
# - 1 .. n: only processes vob/cell ids from this angle
# - v1 c1 .. v99 c99: processes the specified vob and cell ids, specifying the cell is optional,
# but then only the cells belonging to the current PGC will be included
# 0 .. en .. cc .. ALL (can be mixed)
# - 0-31: stream number
# - en, hu, fr, ..: stream id
# - cc: closed caption
# - ALL: everything
# CLOSE:
# - the progress dialog will close itself after finishing (optional)
# SHOW:
# - shows config dialog when complete (optional)
# RESETTIME:
# - if you want to index a specified vob/cell id and not the whole PGC from the beginning,
# then the timestamps will start counting from there (optional)
