I have a PC 290e too, and results are good.

I'm afraid it's no longer true that all DVB-T2 HD in the UK arrives on 
one mux.  In general I record in HD only when testing or, rarely, when I 
think the subject might justify it, but here, with only one HD-capable 
device, I can't record eg BBC 4HD or BBC News HD at the same time as any 
of the other main HD channels.

...and my earlier comment about unplugging a USB device may need 
mythbackend to be stopped too.
