Hi I just bought the 2000t and Im having the same issue. It shows red when off and when recording, but I know just now its recording, because its set to record at this time. Im using a scart as my current tv has no hdmi. If I press the on button on the remote the red light blinks, but the pvr doesnt come on, seems a completely ridiculous situation tbh.
On a side note....
On my old Toppy when I was recording and going off to bed, I could just press off on the remote, a box would appear saying "Do you wish to cancel recording" and give you a Yes or No choice. I just turned the TV off with this option still on the screen, this meant that when the recording came to an end the Toppy would turn itself off. Anyone know if the Humax does the same thing, Ive not had the chance yet to find out.
