Being a media server which will play practically any digital video format, and deliver it to your TV in HD quality, the Popcorn Hour A-110 Networked Media Tank (NMT) has developed a cult following amongst networkers and torrent freaks.

A step up from an earlier model, the A-100, it's even prompted forum comments such as 'I love mine more than my wife.' And after using one for a few weeks, I can see why.

Of course, it helps if you're PC-savvy – its terse instruction booklet can be bamboozling. However, before long you'll have the NMT on your home network and be transferring all sorts of digital media to any connected device, be it PC, laptop or networked TV – much like a NAS box.

Where it differs is that it also connects to your AV system via HDMI and digital audio allowing you to watch stored video, listen to music files, etc.

But why use an A-110 rather than a full-blown lifestyle computer? Well, it's smaller, quieter, and cheaper – just the thing for your living room. In many ways the A-110 gives you media centre PC functions without the hardware or reliance on Microsoft Windows (it runs on the Linux OS).

Supporting both UPnP and Samba protocols, it can see and be seen by pretty much any device you have networked, included the Xbox 360 and PS3; it will also access files stored on USB devices, via a front-mounted slot.

A raft of very cool 'Web services' are available, too, via the simple yet elegant menu system, including the online Media Service Portal community (which allows you to browse YouTube and scores of other IPTV services), and Saya TV, a sort of video blog site.

The possibilities seem almost limitless. In just days, it ousted my fuddy-duddy conventional NAS box, and began to give my subscription box a run for its money. Our sample from Ripcaster.co.uk shipped with a 500GB drive, but even without an HDD it can be used to stream media and browse Flickr etc.

Install a drive, though, and you can even torrent directly into the box, using sites like Vuze to quietly download hundreds of hours of fascinating TV (I only looked at fan films, honestly), while your PC does something else.

The A-110 can take up to a 1TB SATA drive (priced at £300). It will handle almost any digital file format you can imagine, including 1080p video formats, and since the firmware can be updated, it will probably support any format or codec in the future.

Output options to a TV include PAL/NTSC, 50/60hz, from 720p to 1080p on the component or HDMI outputs. The A-110 is technically capable of sending DTS-HD and Dolby TrueHD to a compatible decoder, but as it can't decode these formats internally, you have to make sure your AV equipment can.

Pop quiz

I found playback of DivX HD files from a USB stick to be very smooth and flawless in quality. However, transfer speed from the internal drive can be slow.

Geeks will waste no time getting into the A-110's advanced functions, setting up favourite websites on its Web Services menu, scheduling torrent downloads, and installing new functions from the extensive user forums.

Technically the A-110 is no slouch. The case is a basic 'cage' with a removable top held on with thumbscrews – containing a motherboard featuring a Sigma Designs SMP8635, and 256MB DDR SDRAM.
