I hope I have just missed something basic here

Received some replacement tuners that now work fine

I do have a issue with not been able to record 2 programs at the same time though
I get timer conflict error

Both tuners work and if I set a recording for 1 channel I am able to watch another channel

But if I try to record something else. Get the above error

Seems strange as the usual no tuner free when both are active doesn't appear and when one channel is recording and i switch to another channel (no channels greyed out)
it clears fine and also can see it switches tuners on the info menu
