Hi Frank []images/icons/default/smile.gif" border="0[/]<P>Yes the set top decoders just change the DVB-T signal back into analog for your conventional TV.<P>However even the true Digital TVs, I have seen some over compression on the channels. Much like compressing too many channels on a satellite transponder, you get reduced quality.<P>Much the same as a digital mobile to digital mobile call. Ever noticed how digitised and 'tinny' it sounds? Same sort of analogy.<P>Cheers,<P>Dave
