Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm having problems with DVD playback. Visuals momentarily pause and sound becomes out of sync when using totem. I setup DVD playback as per the Ubuntu 5.04 getting started guide (running ubuntu 5.04 as my distro).
Running 32bit 2.6.10-5-k7
kernel on AMD64 3200+ ATI radeon graphics with fglrx up and running (around 2000fps in glxgears). Playback from harddrive is good so looks like DVD drive.
Heres the current info I think? is important:
Timing buffered disk reads: 6 MB in 3.06 seconds = 1.96 MB/sec
markw@markhome:~/dist$ sudo hdparm -T /dev/hda
Thanks for the reply.
Ive tried hdparm -d1 /dev/hda but get the following error (both as normal user and as root)
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
Sorry if the post was confusing (it wasn't meant to be) I was trying to give as much info as possible.
I'm trying to show the system info on my DVD drive (hdparm -i etc) and my current read stats (the other two lines).
ensure that you are logging in as root on a non-X console, or using "su -" instead of just "su" to avoid any nasty permission hangovers. other than that i've only seen issues like that when a drive is using ide-scsi emulation to run, i.e. it's a cd burner. that said there wouldn't be a reference to /dev/hda normally if it was. is this a cd burner with ide-scsi on it? if so and you're on a 2.6 kernel, then you don't need it at all and you can remove it's use from your bootloader config.
The program totem is based on mplayer's code is not great at keeping audio and video sync. Try Xine or Video Lan Client. Xine and Video Lan Client has excellent sync even on a slow computer. However it seems that the kernel does not have support for DMA or a certain component that is needed for DMA to work. You will have to configure your kernel and re-compile it.
