The VideoLAN Forums

DVDs are currently unwatchable on my machine, as it looks to be reading the disc at 5FPS, but when I play back the same section it plays it much smoother, but insanely fast.

I am using ubuntu 5.04 - 32 bit on a 64-bit HP zv6000 laptop.

Hmmm,

Maybe some hdparm problem (Is the drive stoping and restarting every second )
Also open the view/messages window and look for errors or warnings

Does this happen with all dvd or just a few? Do they play well with another player

Is DMA enabled for your drive? You can check by typing "sudo hdparm -d /dev/cdrom" into the console (assuming /dev/cdrom is the path to your DVD-drive).

I too am experiencing choppy video, the audio is fine though. Is this something that I can install? I should explain that i am pretty new to Linux, so I don't know many troubleshooting steps...

I don't know if this is helpful, but I am running Fedora Core 4 on a Mac PowerBook G3...

Code: Select all

[root@FD4-PPC user]# sudo hdparm -d/dev/cdrom sudo: hdparm: command not found

I think your distribution don't use the sudo-system. Just type "hdparm -d /dev/cdrom" as root. (If that still doesn't work, you could search with google or try to ask in a Fedora Core forum -> How to enable DMA?)

If you type "hdparm -d /dev/cdrom" an get something like this: then you should edit your hdparm.conf. You do this by typing (still as root): or depending on your system (Gnome or KDE). Of course you could also use vim or emacs.
Go to the end of the file and add: (Assuming your DVD-drive is located at "/dev/cdrom")
