Recording and having signal problems

[tool37]

I have bh 1.7.3 running on my duo, when I record a channel on fixed dish (tuner b), and then switch to motorised dish (tuner a) to watch a different channel, the signal keeps dropping from 90% down to 0% and vice versa, but if I'm not recording and I switch to another sat on tuner a, the picture is ok with no signal loss, I have noticed issues with other img's when recording, anybody had the same problems with this image or is it just me

Sorted, reflashed and new install without personal backup, signal is perfect and while recording aswell
