Using the DTV MagicBox and VisionDTV Mini Ter

Installing either of these two devices is a piece of cake - Plug in either the PCI card or USB device as appropriate, and run the setup program from the provided CD to install the drivers and software. You may need to reboot, but after that, you're ready to go!

The software supplied with both devices bears more than a passing resemblance to Intervideo's WinDVB application - To be honest, I'd be hard pressed to see any differences between this and WinDVB save for the logos. Of course, this is no bad thing - Intervideo have a history of delivering decent media products, and WinDVB is no exception.

As you can see, the user interface is very similar to most media players, so you shouldn't have too much trouble getting around. The main console for controlling the software features the usual set of controls for playing, recording, pausing etc, as well as channel up and down buttons. Across the bottom we find seven icons representing, from left to right, the players preview mode (which shows stills of a number of different channels at one time), teletext functionality, access to the EPG (Electronic Programme Guide) available with terrestrial digital TV, access to the list of available files recorded by the player, access to the player's setup properties, screenshot capture facilities and finally access to your list of favourite TV and radio channels. The main 'LED' display shows and allows adjustment of volume, as well as two bars representing signal strength and quality. Sadly though, the teletext functionality isn't available to UK users.


Of course, the first thing you'll be wanting to do once the device and software is installed is actually scan and set up the available channels. Unfortunately, the provided software doesn't prompt for this automatically on first use (It would be nice if it did), so instead you need to access the properties page to find the DTT Setup tab. From here, just select your country (Or choose to scan all available frequencies), apply your selection, and hit the scan button. The software will then do the rest, scanning available frequencies and adding in any channels it finds to the selection. This process typically takes only a few minutes to complete, and you should then find yourself with a plethora of free-to-air channels at your disposal.


As well as timeshifting abilities (i.e. hitting the pause button to 'pause' the TV feed you are watching, then hit play on your return and carry on where you left off), both of these Twinhan products also allow for the straightforward recording of video. Recordings can also be scheduled, giving the software some VCR-like qualities. Simply select start and end dates and times, and pick a channel, and the software will record the video feed as specified. Unlike some TV tuners, where picture quality and the codec used (i.e. AVI, MPEG) can be specified, these two products only use MPEG-2 - The digital signal received by the device is already in this format, so rather than requiring the need to re-encode it, the stream is simply 'dumped' straight to the hard disk in its original form, thus retaining the same quality as the original broadcast. Twinhan estimates that a single hours recording will take up between 1.6 to 1.8GB of hard disk space, so make sure you have plenty available.

This particular property screen also allows you to select a folder to save your recorded files to, as well as specify a maximum length of time timeshifting should be allowed to take place for before automatically ending.


Finally, the properties of the software also allow for some control over contrast, saturation, brightness and the like, as well as some more miscellaneous options, such as making sure the EPG operates in Greenwich Mean Time, enabling or disabling the remote control, and passing the audio through the SPDIF output on your soundcard (if you have one) in the digital AC3 format.
