[mythtv-users] How would you handle the kids leaving Live Tv on all the time?

[Rick]

Hi,

I was wondering if there is a way to "time out" live tv viewing after 
say X hours ?  With the recent Comcast switch to digital, the only real 
way we can watch tv is using Myth.  (That's because Myth has the 
tuners).  The kids are not in the habit of exiting the live tv screen 
before they turn off the tv.  Is there some way I can prevent Live Tv 
from endlessly recording?

Thanks,
Rick
