OK, now for the bit that may actually be useful. Working out how to detect useful programs may take longer than actually doing it manually.
I've reluctantly come to this conclusion myself. Shame though!

Indeed!
(Actually there are a few live broadcasts where I had a moment or two of "fame" which I will keep, but as far as I know keeping these for personal use is fine anyway. Any films/shows that I recorded and wanted to keep I would in any case seek out a DVD or similar just for better quality.)
Having worked out the beginning and end time, VLC has a tool that lets you start the start and end time of a playback - you could use that. VLC also has a record button. When you press it, it records from the time you press start until the time you press stop. This creates a new video of the bit you wanted. I think though that this happens only at 1x playback speed (but I could be wrong), so once you've found something, it'll take a while to extract it.
I think there are better tools for extracting chunks for video into new files but I haven't reached that stage yet.
I guess it depends on the power of your computer, but in the past I have tried other video editing tools and tried to cut up an existing video but my Laptop is just too slow to do them justice - it spends ages coding/transcoding.
My work laptop is fairly powerful and seems able to cope; dropping all the video files to an external USB3 drive keeps it separate from work. I am getting several errors from ffmpeg suggesting dropped frames but I think I need to tweak the settings to fix that. For now I'm happy just to get the content off, I'll revisit any tapes I actually care about.
