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've stopped, because both of my UNknowledge of video in general and VideoForLinux in particular.
Now I don't know if there is a wrong codec, or my card is simply unsupported, or I made a mess with mencoder or xawtv, or I should simply follow the hint of mencoder.
Also, I wondered a while if I should post this in Hardware or Software forum, because I don't know where the problem belongs.
Distribution: Ubuntu, also Suse and Mandrake sometimes
Thanks and more info
before all, thanks for the answer.
Forgive me for the late in response, I've not always the access to Internet.
I'm using a small external device called "video grabber", that accepts in input an RCA or a composite signal, and giving in output audio on a common stereo jack, and video on USB.
I bought it with the goal of transfer my VHSs on DVDs, and to get TV signal via my digital decoder, both using an adapter(SCART->RCA).
The brand is Empire, the device is named "DVD Video Grabber USB 2.0", also if I know that this means nothing, but just to give an idea of the type of device it is.
The main problem in understanding what to do was that the manufacturer gave no information on the kind of output the device gives via USB, teaching only to install the bundled program, connect the device, set up the drivers, and use the program. Searching "video capture" or "video grabbing" gave me hints on TV cards that were able to tune on different channels, or on cards that use FireWire interface to connect to VCR, and I wasn't able to detect what and where those hints apply in my case.
So I tried to feed it to my Linux (Ubuntu 6.06) hoping that it could understand it better than me, and seems that v4l read something and can get many informations correctly, but then I stopped were I wrote before.
A question about your answer: do you think there is a specifical optimal place to put the suggested line? Or should I put it in a standalone file?
Thanks in advance.
P.S. I'll try however to find a place to put it, and will report what will happen.
