[directfb-users] problems with real time clock


i just tried to use mplayer with directfb. While i can see the video i
get the following message to /var/log/message and also to the console:

"rtc: lost some interrupts at 1024Hz"

and the video playback from dvd is not as smooth as it should be. It
seems that there are a lot of dropped frames. 
Looking at /proc/interrupts after ~60 seconds of mplayer replaying a dvd

  0:     354888          XT-PIC  timer
  1:       3980          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  3:          0          XT-PIC  serial
  5:     827910          XT-PIC  saa7146(0)
  8:         67          XT-PIC  rtc
  9:       6285          XT-PIC  eth0
 10:       5723          XT-PIC  EMU10K1
 12:       8143          XT-PIC  PS/2 Mouse
 14:      48412          XT-PIC  ide0
 15:        554          XT-PIC  ide1

you can see, that there are only a few interrupts on rtc.

I am using a matrox g450 and a 900 MHz Athlon in a Asus A7v board.

Using tvtime with the --driver=DirectFB yields the same problems.

Has anybody the same problems or perhaps already a solution ?

best wishes
