Changing channels, but NOT changing channels

[petestrash]

Firstly, are you using a Set Top Box as your input, or the inbuilt tuner?

I've moved this thread, as it's not really a guide issue.

Hi Pete. Unsure if I'm doing the wrong thing to replying to it, now, then.
Yes it's an SD Foxtel box. Not the inbuilt tuner.
The first couple of times I rebooted it would play nicely but I'm now thinking that's unrelated. I can't rule out the image, though, because this one has set a new longevity record.
I always check the IR port and blaster positions and they're all good. I wondered about the IR blaster but read elsewhere here that either they work, or they don't and of course the GUI is receiving commands and saying it's changing channels, just not actually doing it.
Ta. Hoary.
