Just some simple changes; one to fine tune the mark position at the start
of commercial breaks(would be useful as a command line option, probably,
since it seems to vary by company/country) and a change to the logo finding
call that seems to somewhat cut down the number of false positives on
Nelonen. If I have the time & enthusiasm I might experiment with some more
changes later. I'll report to the list should I find something useful.

Changes attached.
