Multiple tuners.. with multiple recording channels (encoders) allowed per multiplex

>Yes, I agree with you for your case. In my case the system rarely records anything
during the day and can be recording up to 4 things at once in the evenings. What this
means for me is that in contrast to you my backend is often recording for less time than
the frontends are playing-back. Great example is if we watch recordings during the day on
the weekend, if we weren't watching recordings the backend would almost never turn on.
This is why I would be interested in shutting down the backend when I just want to watch
what it has recorded (or what I have downloaded).
My solution was to build the mythtv backend into an already existing fileserver box (or
should I say NAS for being trendy...). That box is also used as a( webserver and some
other applications .. so it was already on 24 hours a day..
It has 3 tuners on 2 cards split to 6 encoders... (although tempted to get another double
tuner to cover all multiplexes in Melbourne). The frontends are only on when they are
being used, they run at fairly low power consumption as (since VDPAU) they only run at
1000Mhz at a very low load(I don't get an issue with jerky motion even though I am on AMD
platform and clocked right down.. I don't know why but it's working very well, even with
Advanced 1x de-interlacing)
>PS: What country are you from? Australia have bugger all on during the day at the
moment; crappy dramas, c-grade movies, judge judy/joe brown/other clones and repeats of
shows like Just Shoot Me or Seinfeld (this might change with the extra digital channels
but I'm not holding my breath).
I hate that... before I had mythtv running Mythtv staying at home sick was like torture
if I was too unwell to get to the DVD store....
Channel GO looks okay but from what I can see they only are going to fire it up from 6pm
in the evenings.. So again, no daytime telly worth recording in Aus..
