Sounds like he doesn't know what S2 is. The icons on the left side are encryption, yes, but there's nothing anywhere on any firmware I've ever seen to indicate if a channel is DVB-S2.
B=BISS, I=Irdeto, S=SECA?, V=Viaccess?, N=Nagravision, CW=CryptoWorks?, ND no idea, CO=Conax?, EPG=has EPG, SUBT=has subtitles (but I don't know if they work), TTX=has teletext, $=encrypted, heart=is on a favorites list. I think the next one is a lock, signifying locked out, but if you lock out a channel, I would assume that you wouldn't be able to tune to it to see this screen appear anyway! (But after all, can we ever accuse the programmers of thinking things through?)
