PS3 as a DVR
BBC managed to put his hands on the PlayTV, the device will transform your PS3 in a DVR, Digital Video Recoder.
Actually that tiny box (connected through USB and with an aerial connector) allows you to record two DVB shows at tim, show a fancy EPG, watch LiveTV with Timeshifting (pause the TV stream and go backward/forward in the stream), schedule programs and... stream those through the internet!
Maybe another good reason to get a PS3, as pointed out weeks ago by suzukimaruti in his great post (in italian) about mediacenters.
