Use v4l2-ctl --set-input to set the input of your device (v4l2-ctl -- 
list-input if you don't know which one to use), then cat /dev/videoX >  
myfile.mpg is much easier than setting up a fake tuner, making sure  
mythtv doesn't use it, then schedule a manual recording. Just make  
sure nothing is scheduled to record while you're using that tuner. You  
can always remove the input connections from mythtv-setup for that  
tuner, restart the backend, then put them back when you're done so you  
know it won't try to use the tune while you're recording from your VCR.
