DLNA is a competing standard against MS UPnp; imho, both are lousy. DLNA compliant means that DLNA aware devices & software can detect each other & do the automatic networking setup. this doesn't mean that recorded shows are without the drm i bet sony will ship the very limited, bloated & buggy software that sony won't support next year for windows xp only. only the psp will be supported as sony will lock the transfered shows to the particular psp devices. i wouldn't be supprised if sony limit the number of psp transfer on same show. the devices itself seems promising if you want to use it to watch not archiving.
