I don't know if this will help you with anything, but on my
system(athlon1200/256mb/riva128zx/8mb/Red Hat 7.1 with
gcc-3.0.4(upgraded it a couple of days ago) dga works much better(better
performance/quality) but I can't get it to increase contrast(or gamma,
whatever it is called, the monitor's options and xgamma don't help me
anyways). Xshm(-vo x11) seems to work better than with xine but still
lower quality and speed(I have to use 16bit colour). For me these are
the only drivers that work well. I guess if one has xv supported card
it's better to use -vo xv. Aren't savage cards supported by
Xvideo(with drivers from s3)?
