[mythtv] ring buffer and live TV

[Felix Rubinstein]

Guys, I finally understood the misunderstanding between us!
Please don't get angry as I'm here to help and you'll understand it in just
one second why.

I don't live in US and the country I live in has different set-top-boxes
than you guys probably have. It has a tuner output and S-Video output as
well.

It doesn't matter what kind of the connection you connect PVR to the
set-top-box, you only have one channel, that is it. In order to switch
channels, content provider provides you remote control which sends signals
to the set-top-box to switch channels internally, my TV stays on the same
channel, the TV doesn't know (as well as myth if it's connected) that
channel was switched, all it gets is a stream of bits decoded for it by
set-top-box.
Once again, myth gets merely a stream of bits, it has no way of knowing
channel was changes or not, it gets only a stream of bits.

That is the reason I'm helpless and myth cannot switch channels by itself.
If I use content provider's remote control I get 4 secs delay for any
operation I do: channel switch, many other popups and etc. I've already told
in the users list, it's like moving a mouse and getting the response of the
coursor after 4 secs. Trust me, kernel hackers would agree with me that it's
unacceptable.

I'm not trying to solve the issue and never told that there is a bug.
All I wanted is to help you that you know there are other set-top-boxes in
the world.
Now if you want my help providing you any detailed info, I'd be more than
happy to help.

Thanks.
