I have a lot of experience with the commercial cutting and editing as I do this when
I use mythburn and I have burned > 100 shows onto dvdrw... I did manually edit the
cutpoints for the show that I have used as an example here and there was about 8
minutes removed which was not the problem. The problem is after the cutting and
lossless trascoding the file is about 7MB larger than it was when it had commercials
which makes no sense to me as it should have been (from my calculation) around 290
MB smaller than the original.
