The best way to find out how much storage is used by Live TV (and 
Deleted Recordings) is to use the backend status page, which reports 
something like:

  * Total Disk Space:
      o Total Space: 2,871,327 MB
      o Space Used: 2,622,210 MB
      o Space Free: 249,117 MB
      o Space Available After Auto-expire: 2,738,828 MB
          + Space Used by LiveTV: 0 MB
          + Space Used by Deleted Recordings: 1,175,834 MB
          + Space Used by Auto-expirable Recordings: 1,313,877 MB

Eventually I'll put in the patch that adds the same information to the 
frontend status screen.

If you want to clean up the Live TV at any time, go to Watch Recordings, 
select Live TV in the left column (i.e. using MENU|Change Group View to 
include Live TV or MENU|Change Group Filter to show only Live TV), then 
MENU|Add this group to playlist, MENU|Playlist options|Delete.  You can 
do the same with Deleted shows to remove them from disk.
