Fixed means the tuners are soldered on and you can not change them.

The plug and plug you can change the tuners so can have all sat or cable or terrestrial.


If money is not an issue than have a look at the Duo2 / mutant and Xtrend 10000 or 8500.

Read up and chose one that suits you.

If I was in your position I would get a cable tuner as well, nothing quite like watching in HD.
