+.I NOTE:
+Mplayer doesn't accept colons so type commas instead in the device ID,
+eg. hw,0,0 instead of hw:0:0)
+Be advised that although you can select any samplerate when using ALSA,
+the LAME audio codec is able to encode only the "standard" samplerates.
+You'll get an .avi file with no sound when you choose an odd
+samplerate and use this codec.
