so i've kinda gathered that the 503 is a repackaged 501 with a couple of new bells like remote, more audio channels, and a removable hard drive (just don't have to open the case).
i've read in some of the other posts about new/old network applications and whether these use java now or only active x still. it seems like scorpion is the only one who knows these intimately... have any input on the difference between these? and are they significanly better than the 761? they seem to average almost double the cost (which still isn't much).
