Re: speed please (was Re: [xine-user] Great Job !!!)

[Steve S. <st...@ma...>]

I managed to get xine to play DVD movies without dropping a frame, but the
solution isn't very nice. I just let xine be (almost) the only proccess
running.
what I did (in case someone needs it):
1) init 3  (=no X for me please)
2) stop any resource hungry service
3) fix XF86Config to set the virtual size of the screen to a resolution
<=1280x1024 at 16bit depth.
4) xinit /usr/local/bin/xine -pfhd dvd://t0c0t0 -- -depth 16

note: my working X setup is 1600x1200@32bit

syncfb doesn't work well, i think Xv is MUCH better (correct me if I'm
wrong).

 When my dvd was connected to my promise controller I couldn't get it to
use dma. There seems to be a bug in the promise driver.
 Now I've got dma working (udma-33 from the motherboard controller).

I use the latest kernel always! (2.4.5 in this case)

I installed it and played around with it for a little while. I didn't see
a way of improvement. Is there anything in that that could make the
difference?
