I believe it will not be available for free.

I like this idea. There had been some discussion on this list some time ago.
I believe that commercials shouldn't be cut automatically, but the marks
should be set. So it would be possible to skip a commercial while viewing or
manually start cutting when the marks are verified. With this method you
won't cut/miss part of the recording.

Don't like this idea. How would you manage the data? There has to be an entry
for every recording any time it started. I mean MovieXYZ at 20:15 o'clock
will have commercials placed different then the same movie repeated at 03:00
o'clock. Not to speak of the movie repeated a year later at another channel.
And finally, how do you want to handle the leading minutes before the movie
starts (everyone can set it to his/her preference)?
