I also have a Humax 9200.
It's flawed but it's great.
For instance there's a bug where if you use the picture in picture while watching a recording it eats up hard drive space which can only be freed up with a disk format.
My favourite button on the remote is the button that skips forward 30 seconds - great for skipping commercials. Unfortunately the button is hidden under a crappy slidey bit of plastic that breaks rather quickly.
Take a look on here:
