Even if you don't hit R you can tell it to keep all live TV as long as you
want, and even dedicate a storage group to it.  I have mine set to a 50gig
storage group, set to keep for 5 days.  That way I can go "back in time" and
"record" live tv I watched over the weekend.

I know I tend to ride both sides of the "yell at mythtv" "love mythtv"
fence, but on this issue the complainers are blowing it out of
proportion.  The basic facts are:

1. MythTV is written for and optimized for recording TV on a schedule.
2. MythTV ALLOWS you to watch live TV.  It is not the primary function
though.
2a. Live TV was even rewritten almost 100% fairly recently (.19?) to
allow it to work better and be more "keepable" instead of a constant
30min ringbuffer
2b. Live TV has had enhancements every version bump, the latest being allowing
them to be in a dedicated recording group to avoid messing with your
recorded programs.
3. From other threads there is at least 1 dev playing with how to make
livetv better.  He/she isn't posting because it's experimental work in
progress.
4. If you have a good, concrete specification of how you think live tv
should work better, write it up properly and post it.
 Just saying "channel changes should be faster" is not a fix.  Saying
"in section X of the code it's doing these 15 lookups which take 4
seconds, it could be doing them in another thread while the IR is
changing channels" etc.
