I have to agree.
Digital quality, can be excellent. Yes, the signal will broadcast using a
normal amplifier box. However every extra 'stage', will degrade the
signal, increasing the risk of pixelation.
Seriously, my current digital signals, run 'rings' round the analog
service. You can see the nose-hairs, on the presenters faces (if this is
your 'thing!), and DVD, is superb. I'd suspect first of all that the
original poster, is using the analog out on the DVD, at UHF, rather than
RGB signalling. I'd then further suspect that the DVD's output is tuned to
a frequency that is perhaps getting interference from channel 5 (a common
effect). DVD, is normally limited by the quality of the player iself, and
the set involved. I'd perhaps suspect that this is one of the cheaper DVD
players, and combined with an analog 'aerial style' connection, is giving
the poor results seen.
I have analog, Freeview, cable, and satellite. Currently satellite has the
best quality (just), unless there is odd atmospheric conditions. Cable is
a very close second, Freeview gives more tendency to pixelation, but for
80% of the time still easily beats analog.
