vidix was already compiled and useable in a mplayer package you had on
your site... at least at one point in time..

should already be a /usr/local/lib/mplayer/vidix on your system with a
handfull of *.so files in it... its these .so files that do it... you
dont need to install any modules...

one of the problems tho is even tho i still have this package i took
it apart from its original form and ran the script in it manually to
install it... (redhat doesnt have the 'pkg' command) so i dunno how i
would get it back to you if you dont have it... (been a while since i
took it apart so i dunno how it was originally constructed)... the
version was 1.0pre5 ... the install script will print (to the screen)
info on where it put the vidix files if you are using the same version
i am..

close X if you use vesa.... (if you didnt already) .. ive never tried svga...

i dont have a riva to test that (closest i have is a geforce 4 w/ 128mb ram)

it always will... but it will be horridly slow...

AGP is just a modified version of PCI... other cards can still get in its 
way...

hdparm -d1 /dev/<dvddrivelocation>

linux turns DMA off -- it doesnt matter what the bios says... you have
to turn it back on..

i dunno if you have hdparm or not tho...

DVD audio is natively at 48khz (or more.. but most are 48) so you
shouldnt need to convert it...
