Okay, so I found the 'v4lctl setinput' command. However, I tried: v4lctl setinput Composite1; mp1e -vv -c /dev/v4l/video0 > file.mpeg but it still only recorded the CATV channel. Event removing the CATV input does not do the trick. Any other ideas greatly appreciated. TIA, Alan Murrell <alanm@xxxxxxxxx>
