DVD play back on a Linux iBook


I finally got my drivers and xine running on my iBook (600 Mhz-G3, 256MB) using Yellow Dog Linux. My video card is an ATI Rage 128 Mobility 8MB. I'm using the 'r128' XFree86 display driver. Under special options i have UseFBDev=true. (This was true by default, btw)

'cat /proc/cpuinfo' reports that the CPU is running at 600 Mhz.

I'm using hdparm -d1 /dev/dvd to turn DMA 'on' for my DVD-ROM.

The DVD movie (Blade Runner) plays back almost fine. It looks like it's losing a few frames in full screen mode. In windowed mode, it looks like it running a bit faster but still losing a frame or two. No obvious tasks are running the background hogging clock cycles.

Is there a way to get xine to report of performance numbers while doing DVD play back?

Is there a way I can ring out a bit more performance with more tweaks or better drivers, etc? Any suggestions would be great. I'm so close.

Thanks!
Jon

Or some xine config options that result in a possible speed up. Or is mplayer possilbily faster?

Also is there a way to have xine always run: hdparm -d1 /dev/dvd before the dvd player starts playing? Thanks!

I do not have any suggestion how to speed up your DVD's player.
If you want to have hdparm working at boot (immediately after) add this line
/usr/sbin/hdparm -d1 /dev/hdx ( hdx is the actual device where /dev/dvd is pointing to)
to somewhere in a script like /etc/rc.d/rc.local or your distro's equivalent.
Hope this helps
Ciao

Cool. Thanks for the tip. I'll try that to get DMA automatically working for my DVD-ROM.
