Trying out Ogle, Xine, and mPlayer all give me choppy playback on DVDs. I enabled dma in my modules.conf. Ogle also gives me this error and I have been able to set the sound driver to anything else. I'm using Mandrake 9.1 on a 1ghz Dell laptop and I would apreciate any help you may have to offer.

ERROR[ogle_audio]: Opening alsa pcm device 'default': No such device
FATAL[ogle_audio]: failed opening the alsa audio driver at default
ctrl: ipc_rmid: Invalid argument

Forgot to mention that I do have libdvdcss and libdvdread installed. Any ideas?

I've been playing w/ hdparm but no dice.

Hope this is some help:

ls -al /dev/dvd
lr-xr-xr-x 1 root root 31 Aug 18 12:30 /dev/dvd -> scsi/host0/b us0/target0/lun0/cd

I'm not quite sure where to start fiddling w/ hdparm on this one....

sounds like a problem I had years ago when I first started with linux, your ide controller may note be supported in your kernel, type dmesg | grep ide and post the output

Try removing the SCSI module. I think the module is ide-scsi so login as su or root type rmmod ide-scsi. Then set up the drive to use DMA. I think your DVD drive is /dev/hdc.You may have to change the link for /dev/dvd.

Use OSS as the sound output instead of ALSA. If your /etc/.asoundrc is not setup properly multmedia players will not work. You can then change the sound output device to ALSA after things are working and you have re-edited your /etc/.asoundrc file.

You may have to download a program to set up your DVD drive to a region before playing any movies.

scsi emulation has negledgable if any slowdown for ide drives, I use it on mine and have perfect transfers.

Well, after Mandrake CRASHED and wouldn't boot, I reinstalled and now DVDs are smooth as butta in MPlayer. Howver Ogle crashes on the below error. I have tried to select als in Ogle using the gui but it crashes. Where do I change it in the oglerc file?

probably somewhere in your home directory, do: "ls -a | grep ogl" and see what it gives you

Here's the error:

Debug[ogle_vout]: resize: 720, 540

I had this once, make sure both your ogle version and alsa version are newest. I *think* that is how I fixed it.

Getting rpms from Freshrpms.net did the trick. Now I need to figure out why my 3D performance sucks even though it's setup properly. Thank you all for taking the time to help me w/ my trivial problem. I'll try to pass the favor on

about 3d performance: just check and see that alsamixer isn't running and if it is kill it and then try 3d.

Turning off KLaptop fixed my 3d acceleration issues. Now I need another laptop battery monitoring daemon. Any ideas?
