However if you've been using your system for any length of time you have
long filled your storage space and *rely* on myth to delete the oldest stuff
to allow you to continue recording new stuff. So there will never be free
space for live tv, so you will never be able to just go to live tv, you
would always be informed that you can't enter live tv because you have no
storage space... Which would be a pita.

If you're using MythTV you *know* that when your storage is full any new
recordings will overwrite the oldest recordings (simplified view).
If you're using MythTV you *know* that when you watch LiveTV it is in fact a
recording that can be ff/rw paused saved in it's entirety from the point you
started watching (or from the last program schedule change, which ever was
the most recent).
So now you know LiveTV is a recording, you also know new recordings
overwrite old ones, so going into LiveTV you carry the knowledge that you
are potentially overwriting old recordings.
