A few weeks ago I was watching TV using a set-top box while also
watching the same channel (using MythTV's live TV functionality) on my
laptop. The time lag was below 2 seconds.
However there is still an artefact I'm trying to fix, which is that
audio is delayed by a few hundred milliseconds relative to video. I've
asked the ffmpeg mailing list for how to delay the audio track of an
incoming stream (as opposed to delaying the audio track of a video file).
