hi, i have a dreambox 500s and its clone the inetbox300

i tried getting some channels last night from eutel 9b by entering all the transponders from my v8 finder 2 (which pulls lots of fta chans from that satellite)
only a few channels were found on the dm500s and inetbox300

are these boxes useless these days? can they not handle modern transmission standards?
is there any point keeping them? can they still be used somehow?
