Hello,

I am trying to find out whether there is any appreciable 
difference in the technical specifications of the digital to 
analog TV converter boxes.  Secondly, are there some which are 
appreciably more accessible than others?  Lastly, do most or all 
have some sort of an inaccessible setup screen when first used? 
If so, will these settings be lost if the unit is unplugged or 
there is a power outage?

Thanks for any info.
