Sounds like a permissions issue. Make sure they work from the command  
line as the same user that runs mythbackend. Also, make sure you're  
using absolute paths to the channel change script as I was bitten by  
that once when I was running as separate users, but it wasn't in the  
path of one of my users but was in the other.
