To date, home DVD recorders have only recorded two-channel soundtracks - usually in Dolby Digital 2.0. This is fine for terrestrial TV programmes (analogue or digital) but does a disservice to multichannel movies.

Sky Digital's movie channels harness 5.1, but the only way to enjoy them with compatible equipment is with Sky - the only Sky box with a digital audio output. The Sky is also a PVR, and was the only way of recording 5.1 broadcasts. Until now, that is.

A look around the rear of the DVDR7250 HDD reveals a coaxial digital input. It's the first we've seen on any consumer DVD recorder, and Philips earns congratulations here. It also handles Dolby Digital and DTS.

Suitably configured, the 7250 will accept (RGB) video via Scart with 5.1 bitstreams from the digital audio input, and combine them to make 5.1 recordings. Great for archiving Sky movie playouts when its hard drive is filling up. Sadly, 5.1 recording, (enabled from the cumbersome setup menus) can only be made in the XP and SP modes. Also, the coaxial input isn't compatible with the Sky 's optical output. Gadgets are available to convert between the two (I used a USB-powered Terratec device called the Vice Versa), but why should we have to? Philips, do your homework!

Philips could not confirm whether the 7250 will be ready for Dolby Digital 5.1 DTT broadcasts, if they appear.

But what about the rest of the kit? Finished in the distinctive Philips DVD style - curved fascias, bright blue-green fluorescents and control discs that glow red during recording - there's little to physically distinguish this innovative recorder from the past. Internally, too, there are some old traits, some welcome, others less so. There may not be HDMI (a tall order for the price) but you do get an RGB Scart, plus a component output to switch between interlaced and progressive. Happily, analogue and (non-upgradable) Freeview tuners are specified for recording TV, onto DVDs ( RW/-RW, -R/ R or dual-layer R) or the hard drive.

The latter is a fairly generous 160GB, which records between 31 and 250 hours depending on which of the seven modes you use. Of these, only the top three and 2.5hr. per single-layer DVD) work at DVD's full resolution (720 x 576). The rest 'halve the horizontal', with a loss of detail. Philips could learn from their rivals here. For two years, Panasonic has been selling recorders with a full-res four-hour mode. Then there's the GuidePlus EPG, which has graced other Philips.

Replacing the 'standard' Freeview EPG, this service is the one way of setting the 25-event timer. Mercifully, GuidePlus does have manual and standard VideoPlus fallbacks. Set-top box control is another possibility. But there are disadvantages. Interactive 'cues' (those annoying red buttons) are burnt into DTT recordings. Furthermore, you can't specify a recording quality for each event. All recordings are made in the default modes. And you have to slug around the menus to change mode, as Philips' handset doesn't have a button for it.

The only editing options are divide and chapter modification - there's no partial erase, so removing adverts is a pain. Only timed off-air recordings are automatically chaptered.
