[mythtv] Simultaneous Recording/Viewing (Two Tuners)

[Risto Treksler]

Two tuner cards raise many interesting questions/possibilities

1)record and watch @ the same time
   -how much power is needed to pull that off??
    so that you can still have a ringbuffer and to pause live tv with one card
    while the other is recording something

2)multiple ringbuffers ?!
   -watch a movie on some channel on one tuner card, press pause
   -switch to different tuner card, and watch the hockey game for a minute
    with instant replay capabilities
    (the 2nd tuner would have its own ringbuffer)
   -switch back to the tuner with the movie and press "play"

2a)this way the current AND the previous channel would always 
    have a ringbuffer going so you can rewind a little to see what you missed.
    (unless of course one tuner is recording something)
    recording conflict resolution would also be affected by multiple tuners
    -option to limit # of tuners available to for recording (1, 2, all)
     so you can make sure one tuner free for viewing live tv
    -only report a recording conflict if no tuners are available to record.

3)seamless switching between tuner cards?
  -same as above, but it might be nice if after pausing the movie
   changing the channel would automagically chacge you to the second tuner
   and changing back to the movie 
   would automagically switch you back to the first tuner
 -everytime you change a channel, you switch tuners,
  so that the previous channel always  has a ringbuffer going,
  unless one ore more tuners are paused

how much of this is implemented?
how much processing power/RAM/hard disk speed is needed to record 2 or even 3 
or 4 shows at once?
