Hi been researching a unit for my car but need a little more advice before hitting buy now

Some of the readers here may of heard of the Emperor Road king car stereo but a little confusion on my part or maybe bad advertising but I will do a little cutting and pasting from the adds

DVB-T information

and other sites state


DVB-T Information :

• Digital TV receiving standard: MPEG-2 and MPEG-4 (100% works, please search DVB-T on wikipedia.com for the coverage of your city)

• Automatic and manual search

• Display: 16:9, 4:3

• Languages: English, German, French, Italian, Spanish, Turkish, Greek, Russian, Czech, Slovak, Vietnamese, Chinese

So my question here would be is there a separate decoder in the tuner or is it all done with software for watching NZ DVB-t or would they both in fact be separate units for different countries ?

These look like a mean machine to have but the site I was going from cancelled my order over the weekend and increased their prices by $ us 100  other places have them $ us 100 cheaper but dont advertise DVB-t MPEG2 + MPEG4

I was just curious as under media player info their is H.264 and MPEG4
