My OTA is hosed now as well. It seems to be the same issue we had before. I can watch OTA programs on my Hopper 3, but live OTA on Joey's has hiccups. Recordings also suffer from those same hiccups.
Hopefully this is just a case of some code being inadvertently replaced with a previous version and will be a quick fix, but again it makes me wonder what kind of testing process these updates actually go through before being released.
