Sorry for the confusion. The coffee analogy applied to the OP who was complaining about a Knoppmyth bug where it sets a ring buffer larger than the partition designed to handle it, which will cause a crash. The example he used was leaving Live TV on all night and waking up to find the system in an unusable state. I say this is not the recommended use because, while live TV works, there are certain shortcomings that are structural and fundamental -- i.e. can't be fixed, at least in the current design. One of these is that the ring buffer is not a standard recording, so that when you change channels, for example, the ring buffer is erased and restarted. This means that when channel surfing, you lose the ability to rewind to a point behind when you switched channels. I understand this is currently being addressed and that the ring buffer will be redone in future versions. Another problem is that there will always be a slight delay on Live TV, and a delay of a few seconds when changing channels. This is because MythTV has to instruct the tuner to change channels, initiate recording in the ring buffer, then initiate playback of the ring buffer. As the whole system is currently being redone, I don't know how this will change in future versions, but I don't think the delay in changing channels will go away. There is also a delay with any digital cable or satellite system. The prefered method for watching something 'live' is record it as a normal recording and begin watching it immediately. Of course watching it immediately eliminates the ability to skip ads, which is one of the main reasons why people build a PVR in the first place. As an example, I use MythTV to watch football games. If I start watching the game at 1:00, I still have to sit through all the nonsense. If I start recording at 1:00 but don't start watching until 2:30 or so, I can get almost the whole way through the game before I've caught up with the live stream. Of course the problem with sports is that the games rarely end on time. This problem is solved by setting the 1:00 game to end 30 minutes late, and the 4:00 game to start -30 minutes early. With multiple tuners this is less of a concern, but if you have a single tuner like me, this addresses the problem when you want to watch games on different channels.
