BTW, I've just been fine tuning School House, tweaking the settings in order to get a 100% detection of all of the commercials in two particular troublesome 720p HD recordings.

The only way to pick up absolutely every single commercial and not any segment of the show was to make the following changes from default:

Force SchoolHouse Mode: Yes

Preselector Method: Manual (even with SH mode, no matter what threshold I tried, percentage always misses one commercial at the start of the 3rd set of commercials)

Preselector Threshold: 50 (60 still misses that one commercial, even with SH mode and manual)

LPIC: 95 (with the default some sections of the HD show ends up detected as a commercial)

I'm extremely impressed to be seeing a 100% accuracy in commercial detection with HD content. To be accurate, so far I've only tried 3 troublesome recordings, but I really think this is going to work for most recordings. Without School House mode Show Analyzer really struggled with HD content. After at least 10 hours worth of experimenting with settings (5 of that with 0.9.1) without SH mode, I gave up and will now always use School House mode for HD content.

Thank you for adding SH mode!

If we can deal with the 1-2 second drift this will be simply incredible!

I'm going to try the current settings on some HD movies and see how well they do and how much drift there is.
