On my system starting live tv usually takes about 2 seconds, changing
channels is about a 2 second process.  Directv D11-100 stb connected
to svideo of PVR 500, controlled by usb serial adapter.

I do not have an explanation for the this next oddity, if I surf with
mythtv and my stream zap remote it is 2-3 second average channel
change.  However, if I use the osd of the stb the system slows down to
about a 8 second delay on any action such as scrolling channels.

I seem to recall a setting in (I am not sure about front or back end)
configuration that has to do with the ring buffer.  The setup help tip
indicates that if the size of the ring buffer is set to high it will
adversely affect the operation of live tv.

You are correct about it being a great piece of software.
