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.

Have been trying to get a microdia web cam to function with mplayer.
All I get is a green screen (static?) with video1 and ioctl errors with video0.
Here is what I use:
mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video1 -fps 15
I have also used -fps 30 with the same result.
dmesg | egrep -i video
[ 4.749297] Linux video capture interface: v2.00
[ 5.204899] usb 4-1: V4L2 device registered as video0
[ 6.375530] bttv0: registered device video1
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 002: ID 0c45:60fc Microdia PC Camera with Mic (SN9C105)
The actual driver is sn9c102 which contains the info in ...105.
Note that video0 is registered to usb 4-1 which I suppose is bus-device but the camera is on 4-2. Also note bttv is on video1 so I should not be using video1 for the camera, yet aside from the green screen I see the numbers turning over behind the screen in the terminal.
Am I confused or else how do I correct my system, 13.37, to accept video0?
I tried that route. Get pretty much the same result. I will be experimenting with applying enable_mtrr_cleanup mtrr_space_reg_nr=1 in lilo as soon as I have time to research it as this I found may clear it up. Hope springs eternal.
