I use 0.2.0-rc3j and it works fine, so I doubt you need a newer IvyTV.

Sounds like someone has an invalid channel change script specified, but 
is using the tuner input.  So, when the channel change script fails, the 
LiveTV fails.

But, I don't know for sure because I need to know what input you're 
using, what type of source (i.e. RF modulated feed from a STB, 
S-Video/Composite from a STB, direct antenna/cable connection, etc.), 
whether you actually have a channel 12, and, perhaps, a few more 
things...  :)
