The delay is simply the a side-effect... Myth takes the raw video 
stream, encodes it, writes it to disk... then the frontend reads it 
from disk (or it's read from disk by the backend & served to the 
frontend), decodes it, and displays it.

That whole process takes a non-zero amount of time; hence the delay in 
LiveTV.
