did you see this pictures from the link that i posted before?
http://free.pages.at/gerti67/pictures/tweak-levels.jpg
levels encrease the gamma without encrease the bright in the borders.
bright and contrast will encrease the light in the dark area too!
but nothing is better than test.
do a sample with levels and another with bright/contrast to choose !
oops...i forgot:
use levels before the "resize".
it will encrease the "light" and compression when resized!
nothing wrong with this values:
Levels(0, 1.3, 255,0, 255)
this is the recomendation from the avisynth manual
"# gamma-correct image for display in a brighter environment"
see in the avisynth 2.5x folder!
