My understanding is that this is because hardware TV tuners create an MPEG2 stream from the analog broadcasts, so you need a few frames in order to create the mpeg2 stream that can be played back, or we have DVB and anyway you need to wait a bit to start reading the MPEG2 video stream from somewhere that can create the full image. In either case there is a small delay. Add the time it takes to do some processes like clean the ts-buffer, show OSD, get channel EPG, etc.For my waife this delay is annoying, she can switch the channels so fast that you can see all of them at the same time . But having the EPG data before actually switching channels makes this delay bearable.
