both are dependent on manufacturer's release. with dynasat, once you have the chip installed already, then you can readily install the software as soon as it is released (some say there were boxes not needing the protection chip). with metabox, they have been kind of slow to release, but somehow managed to get a stable version of their software out for users too. there are other boxes which released their software within two days of the last ECM attack, such as victory, ns3000 etc. pc dvb-s plugins got their working roms within 4 hours of the attach. your choice.
