I have used this method for over a year now and I find that it is good
on some shows and bad on others. One example is a soap opera that I
record 5 days a week for my girlfriend requires manual editing for the
commercials more than 75% of the time and I also have to be careful as
it has been known to delete several minutes of the show. However when
I record a show on animal planet there usually is very little or no
editing necessary.

I'll check into that. Thanks for the info.
