xvidcap is a great, free tool for handling video capture and audio overdub. It has many of the features associated with pricey tools like Camtasia.

Installing xvidcap into Ubuntu Gutsy requires a few package adds that are not on the ship DVD or are there but at unsupported levels.

Steps to install xvidcap are as follows:

1. Obtain the most recent stable version of xvidcap from http://sourceforge.net/projects.xvidcap/ . I used xvidcap_1.1.7rc1_i386.deb
2. An atttempt to install this package results in two unresolved dependencies. liblame0 and libpango-1-18.3 (libpango is installed at 1-18.2)
3. To obtain liblame
   
   http://packages.ubuntu.com/gutsy/i386/liblame0/download
4. libpango requires libpango-common. Get libpango
   
   $wget http://launchpadlibrarian.net/10117979/libpango1.0-0_1.18.3-0ubuntu1_i386.deb
5. Get libpango common
   
   $wget http://launchpadlibrarian.net/10117977/libpango1.0-common_1.18.3-0ubuntu1_all.deb
6. Switch to root
7. Install liblame0
   
   dpkg -i liblame0<tab>
8. Install libpango-common
   
   dpkg -i libpango1.0-common<tab>
9. Install libpango
   
   dpkg -i libpango1.0-0<tab>
10. Install xvdicap
    
    dpkg -i xvidcap<tab>
11. Verify xvidcap works
    
    Open a terminal window and typexvidcap
