I don't know how common this is but the remote for the TV has interesting side effects. Use the TV remote to try different aspect ratios and the Humax changes to the next channel along. Doesn't bother me, I can always change the channel back but I'm curious; is it possible to alter TV and Remote frequencies so that they don't effect the Humax? I could move it a wee bit but I don't know how wide the remote receiving area is.
Plus I'm only just getting used to not triping over it where it is.
