I was trying to say (in my sarcastic way) that multirec will continue  
to include more features as time goes on. On the dev list I remember  
seeing that the HDHomeRun is likely to be the next supported tuner. As  
soon as a developer has time and a need for it, I'm sure it will make  
its way to analog tuners. Since you are using a version with multirec  
in it, I'm sure you saw these same messages on the dev list. :)
