Is this fact or guess?
My tivo series 1 had a latency of approximately 800 ms iirc.
So, after the channels is changed (which takes time with the ir blaster) it
took that long for video to actually change.
Tivo uses a hardware codec and does not buffer up any data.
Myth fe seems to want to have a big chunk of video before it starts playing.
This helps when the be is busy and sometimes can not keep up.
It takes about 3 seconds for a recording to start playing. This is for the
same reason, Myth wants a good chunk of data before it starts playing.
This is with a remote fe.
