+Here are just a few tips:

+<listitem>
+<para>
+Use the <option>channels</option> option. An example:
+<screen>-radio channels=104.4-Sibir,103.9-Maximum</screen>
+Explanation: using this option, only the 104.4 and 103.9 radio stations
+will be usable, and there will be a nice OSD text upon channel switching, displaying the
+channel's name. Spaces in the channel name must be replaced by the
+&quot;_&quot; character.

+There are several ways of capturing audio. You can grab the sound either using
+your sound card via an external cable connection between video card and line-in,
+or using the built-in ADC in the saa7134 chip. In the latter case, you have to
+load the <emphasis role="bold">saa7134-alsa</emphasis> or 
+<emphasis role="bold">saa7134-oss</emphasis> driver.

+<para>
+<application>MEncoder</application> cannot be used for audio capture, because it
+requires video stream to work. So your can either use arecord from ALSA project or 
+use <option>-ao pcm:file=file.wav</option>. In second case you will not hear any sound
+(except you using line-in cable and have switched line-in mute off)
