Rant mode on: DRM has always been a bane to both consumers and suppliers, and the sooner suppliers realise that, the better. We're specifically looking at Sky here.

With its attractive selection of television channels and fancy-pants set top boxes, Sky is almost single-handedly responsible for thrusting the next generation of television into the living rooms of the UK, and not always to the tech-literate.

In fact, Sky has been specifically targeting a more mature audience with its Parkie-endorsed tales of Sky+ being luddite-proof. But us non-luddites, looking at Sky's technology from a rather different angle, smell a rat.

You can't actually transfer your recorded files to any other device because they're encrypted; essentially they're copies of the incoming transmission that the set top box decodes with the help of your viewing card. Actually shifting a recording onto, say, a portable device would involve a long-winded process likely to involve a DVD recorder and several conversion steps – not exactly convenient.

We can't entirely blame Sky for this. Encrypted streams are, sadly, a necessity of subscription-based broadcasting, and a live conversion is out of the question with such little processing power. However, we can shake our fist at the DRM for denying us the simple pleasure of device-shifting.

As we've found while testing Humax's Foxsat HD Freesat box, such awkwardness is not restricted to digital recordings or even to subscription-based channels. There's no hard drive in the basic Foxsat-HD, just a stack of MPEG processing power and a swathe of relevant components.

But it doesn't avoid the spindly fingers of DRM: try to watch a 'restricted' HD broadcast over a component connection – a perfectly reasonable request, we think – and you'll be shooed away, forced to watch over HDMI or drop down to standard definition.

This is the forward-thinking equivalent of a 'no recording' broadcast flag, technology that has been possible and indeed discussed for years, but never implemented. HDCP is coming into its own.

With that in mind, initial forays into the world of the Topfield TF5810PVR are quite refreshing. It's open, for a start – no encryption, no lock-outs and a section in the manual that clearly explains how to copy your recordings to your PC via USB. VLC happily plays them without conversion, and it's easy enough to remould them into other formats.
