I live in Southern California.
Last fall we had a particularly nasty fire storm roll through town. Maybe you caught it on the news. <http://www.youtube.com/watch?v=9QYT3ASpKSU>
Our house was directly down wind and right in the path of the fire.

News coverage was spectacular but of little use for determining exactly where the fire was heading.
Using MythTV, I was able to record four broadcasts and by jumping between them and studying mapquest, determine if and when it was time to hop in the car and run.
Had I been "channel surfing" I most probably would have missed the aerial shots that showed landmarks I recognized in order to track the fire's progress.

I didn't hear about 9/11 until I was in my car, on the way to work... don't watch TV workday mornings...

Yes indeed. At least here in Australia where all the Myth people I know just
record FTA digital channels, all tuner cards are essentially equal as far.

I've never understood why MythTV schedules the input card along with the
show to be recorded. Why not just schedule the recording ahead of time, and
then pick the best available input "live", i.e. when the recording is about
to start?

If no input is available to record How We Built Apollo 11 because the better
half just tuned into Biggest Loser live, then perhaps a pop-up can give the
user the option of which to persevere with.

It should still be possible to predict scheduling clashes, based on the
assumption that no-one is watching live TV.

[.Sorry for getting in rather late on this thread, but this issue is rather a
pet-hate for me about otherwise-fantastic MythTV]

Cheers,
Justin.

I have kids, 3 and 6. There is a frontend in the living room
which is pretty much exclusively for them.

Nobody in the house watches LiveTV, and the kids don't really
get the concept of commercials.

I like that a lot.

Re: LiveTV conflicts with scheduled recording - despite unused tuners on the same box! [In reply to]

In my house LiveTV is used about as much as recordings.
The main reason why LiveTV is still used in my house - is that mythtv
sometimes fails to record a show - but tuning into the same channel
using LiveTV always works. (note: This is NOT because there's any
conflicts or anything... MythTV simply does not always tune correctly
- and it has NO error handling/correction for that!)

So, if there's something I REALLY need to watch, I find LiveTV more
reliable compared to making a recording!

MythTV is still only in version 0.21 - so one should NOT expect it to
be ready for everyday use!

Nice to see a user acknowledge that.

But I would still try and figure out why you don't have reliable tuning. Even
using an IR blaster I have never had a mis-tune in many years.

There is no feedback to Myth that a channel has been properly tuned, as you
mentioned. Since most of the devices being tuned provide no return
information that would be hard to do without a human verifying the tuning.
