I wish I could agree, but for me LiveTV has gotten much more instable  
since 0.25 and this didn't improve with -fixes either. I'm curious to  
test 0.26 if that improves anything, since I didn't have time to track  
the issues down and report them back yet. That's why I didn't complain  
yet, it's useless if cannot provide more details.
Right now it's pretty much hit-and-miss whether LiveTV works, which is  
kinda annoying with watching the Olympics, which is a perfect use case  
for LiveTV for me. Even worse, once it fails, I can usually only  
recover the BE/FE by a reboot.

Probably.

Unlikely, if only the MythTV version changed that turned LiveTV from  
mostly stable to mostly unstable.
