I don't know how many times we have to say the same thing for people to understand why autotune is desirable. It doesn't matter the slightest that the unit being used is a DVR.
I want to be able to record to DVD LIVE, not record to DVR, then later play it back, thus tying up my DVR for a simple operation that could have been done automatically in the first place.
If the goal is to do an immediate archive, the only easy and efficient way to do so, is to have the auto-tune function. Then all one has to do is tell the DVD recorder what time to start and stop a recording...viola! Done.
Because the DVR will record in the background, there is no way to be certain that the show in question will be in the foreground ...so you end up recording the wrong show.
Auto-tune solves this problem, no extra steps, no games to play trying to force a specific tuner to the foreground, nada...it just works. Nothing else does.
So, please, stop telling us we don't need it, it's already there, etc. etc. , ad nauseum. It isn't there, the work arounds are cumbersome and do not work reliably (ask Earl, I did some testing of this for him and the conclusion was....ooops, won't work reliably).
Autotune has a function that cannot be duplicated without it, that being the ability to force a program to the foreground so its video appears on the output connectors for recording to DVD in real time.
