Hi Gerald

I had vaguely similar problems converting from 0.24 to 0.25.  In my
case, I deleted my tuners and input sources and completely reinstalled and every
thing has been great since.  

Before doing this I thought 0.25 was a disaster and now, it is working
basically perfectly.

Good luck,
Dave
