Bare with me here i have been having big issues with every Firmware update post 1.12.14
My wdtv smp when updated past this firmware revision will intermitently loose its signal to the TV and AMP (screen will go blank and amp will loose the signal and then get it back this will happen regularly)
While on the 1.12.14 revision i do not have this problem and the SMP works flawlessly on any firmware after that point it does not.
