A couple of points; a mistake I made (mea culpa) - there is an EPG search; it's just not immediately obvious.
Fast forward is tolerable at the highest speed, though you do get some of macro-blocking. There are other options worth using too, though. First, there's resume playback, so you can jump back to where you were. And the same screen allows you to enter a number of minutes to jump to and then start playback. Finally, there are the skip buttons; admittedly they are limited in duration, but the combination of those will likely cover most common needs.
As for the score, I think it does deserve the figure it got; we do have a standard way of calculating the ratings for RegHardware. Essentially, this doesn't offer as much as the Humax, but it does provide features (notably Dolby Transcoding) that are missing from some of the others I've looked at.
It's got a pretty straightforward interface that should be simple for most people to grasp (even if they don't find the EPG search), but lacks some of the extras found on, for instance, the Digital Stream or IceCrypt boxes.
