what do you mean without pc? no need for pc to configure anything? you can do that with dreambox if you want, use tuxbox commander plugin and use your remote to edit your configuration files. you must be a masochist to do that.
otherwise, buy one of those using dongle and a dish pointed to another sat for the CS stream (dual tuner receivers) but the stability, let alone the longevity of such service is not guaranteed.
a dreambox is a pc in itself, operating on linux OS just like all other sharing receivers. so you really need a pc for configuration every now and then.
