I have been playing since I posted my last message. My sound card is a
ForteMedia FM801 (SB16 clone) that I have working using Alsa 5.11.
Alsa offers a dummy sound card option that didn't me make the slightest
bit of differance to the quality of DVD playback other than I don't get
sound. This leads me to suppect that PCI bandwith as suggested on here
isn't my problem. My Video card is APG and there for the only traffic on
the PCI BUS is sound?
Is having this in my /var/log/XFree86.0.log relivent?
Symbol xf86CreateI2CBusRec from module /usr/X11R6/lib/modules/drivers/r128_drv.o is unresolved!
Symbol drmScatterGatherAlloc from module /usr/X11R6/lib/modules/drivers/r128_drv.o is unresolved!
Symbol drmScatterGatherFree from module /usr/X11R6/lib/modules/drivers/r128_drv.o is unresolved!
I Think that DRI is working as I have /proc/dri but don't have anything
saying that it is in /var/log/XFree86.0.log
I have also tried all the video modes on MPlayer listed below and all work
much the same for speed. I'm running MPlayer 0.50 that was released a few
weeks ago and found it much better than 0.18 that I was using. I have also
used vlc and found the playback speed to be much the same. vlc has a better
(GUI) user interface and much quicker CSS decode key.
The only conclusion that I can draw at the moment is that my ATI XPERT
2000 isn't fast enough for 100% DVD playback under linux. I suppect that
this is a driver issue as I'm sure that it would work fine if I had the
will to install windows. This card also offers some hardware DVD decoding
under windows but have been unable to find any linux drivers.
I have overclocked my system BUS to 145MHz (from 133MHz) which has helped
but still not as good as I would like.
Available video output drivers:
xmga X11 (Matrox G200/G400 overlay in window using /dev/mga_vid)
mga Matrox G200/G400 overlay (/dev/mga_vid)
syncfb Matrox G200/G400 Synchronous framebuffer (/dev/syncfb)
x11 X11 ( XImage/Shm )
gl X11 (OpenGL)
gl2 X11 (OpenGL) - multiple textures version
dga DGA ( Direct Graphic Access V2.0 )
sdl SDL YUV/RGB/BGR renderer (SDL v1.1.7+ only!)
fbdev Framebuffer Device
png PNG file
null Null video output
odivx OpenDivX AVI File writer
pgm PGM file
md5 MD5 sum
mpegpes Mpeg-PES file
