Are you only using one not both.
Can you take a screen shot of your tuner configuration. Menu, setup, service searching, Tuner configuration.
You say this is happening with openwebife so are you streaming while it's trying to update that maybe why each service needs it's own tuner so it could be conflicting using one tuner for abm , 1 for live tv and 1 for openwebife you can only use 2 at the same time
