Because a program transition occured at the top of or at the half hour.  
So, imagine you're watching some Friends on LiveTV and after a while you 
realize, "Hey, this is the episde where Joey sticks his head in a 
turkey--I've gotta record this."  So, you hit R and enjoy the episode.  
Then, the program ends and the Nightly News at 6:00 starts up.  Since 
you're interested in what's happening in the world, you watch that, too.

With your approach--when a user hits R, every TV show that airs until 
the user exits LiveTV is recorded--the News will be recorded.  And, if 
you finish the News and stick around to see what's on next and realize 
it's Judge Judy, so you exit just after Judge Judy starts, Judge Judy is 
not LiveTV, so it gets recorded--*even* after you exit "LiveTV".

The problem here is a) you have no guide data for that channel and b) 
you didn't tell Myth how long the "program" really is (with a Manual 
Recording rule).

It's not part of a recording.  It's a complete show, as defined by your 
guide data (or, more precisely, your lack of it).

No.  The user should *never* use LiveTV with the R button to record from 
a channel with no listings data.

You do realize that if the content you were recording was a 10-minute 
piece and you entered LiveTV to begin recording it at exactly 32 minutes 
after the hour and hit R, you would be recording a 28-minute 
episode--even if you exit LiveTV.  That means you get the 10 minutes of 
content and then another 18 minutes of "whatever happens to be coming 
into the input" (possibly "Darkness and Silence").

So, just do the same with your Manual Recording rule...  Think, OK, I've 
got a VCR tape that holds 2 hours of content, so I'll just set up a 
2-hour recording (or 6-hours or whatever).  If I find that the content 
is only 1 hour, I can simply go to Watch Recordings, select the 
recording in progress and use the Action popup (INFO button/hit I) to 
Stop Recording (I think it's under "Recording Options" in that menu).

Or, if you're not watching the recording in progress (so you don't know 
when it ends), use the editor to find the end, set a cut point ("Delete 
after this point")--and take the opportunity to clean up the beginning 
of the recording, too.  Then, start transcoding it.  Assuming an MPEG-2 
(i.e. you used a hardware encoder like the PVR-x50/500), you can even do 
a lossless transcode to just cut out the garbage.

Or, use one of the other many video editing applications.

If you're using Myth, use Manual Recording rules.

Please, this time, read the posts I linked:

and

They're only hard to use until you use them and realize how easy they 
are to use.
