My brother has a tv tuner that has not been used. Now, i try to use it in Ubuntu 12.10. I try to search linux driver on hardware website but i am not found the driver. But i found an ubuntu package that can use for watching tv, the package called tvtime. To install this package just run

sudo apt-get install tvtime

tv tunner

Although there are a tvtime package, but the application does not run so well for my gadmei. I think because it was too old, about 5 years ago. There are a few things I do to fix the application to be compatible with the hardware I have. The problems that I experienced after the installation is

TVTIME not detect the video source from Gadmei. By default, tvtime detect video source such as a webcam on the laptop. We can figure out the problem by running tvtime in a terminal. Would appear an error message like this

videoinput: Driver won't tell us its norm: Invalid argument
videoinput: Can't get tuner info: Inappropriate ioctl for device
    Your capture card driver: uvcvideo [Laptop_Integrated_Webcam_2HDM/usb-0000:00:1a.0-1.4/19
    does not support full size studio-quality images required by tvtime.
    This is true for many low-quality webcams.  Please select a
    different video device for tvtime to use with the command line
    option --device.

To fix this, go sourcelist of tvtime in the folder / etc by running the command

 sudo gedit /etc/tvtime.xml 

search for code below

 <option name="V4LDevice" value="/dev/video0"/>

Change the video0 to video1 so the code will be look like this

<option name="V4LDevice" value="/dev/video1"/>

Before start watching we need to scan the tv frequency on our location :D. So we can save the frequency of  tv station in our area. To scan tv frequency, run this command to terminal

 tvtime-scanner

tvtime-scanner

After that just rung tvtime and you will can watch television in your ubuntu desktop.
