I also used Project X some 12 years back for a while until finding a 
commercial product called VideoReDo.
VideoReDo has the Ad Detection technology looking for changes in scene, 
fades to/from black and audio levels.

Unfortunately Ad detection just isn't accurate enough to use 
automatically and in the end swaps from cutting the ads to cutting the 
program and leaving the ads. (some ad breaks have Fade from black in middle!
Manually marking the program with a good UI (keyboard shortcuts) I have 
found to be much faster and accurate.
The station bugs are really good human tell-tales between ads and program.

Each station is different and needs its signal to be analysed. Sometimes 
they leave markers in the vertical interval.
At one stage Win had line 7 as a white line during remote program, I 
built a hardware detector for this to record Star Trek in the early 
morning for a while, but eventually it disappeared.  Also sometimes the 
Ads from remote network would appear too using this method as they were
