True that BluRay movies are generally 24p, but 24fps motion picture film has almost equal durations of blackness between each frame as the shutter passes over the film gate, whereas your LCD/plasma screen at home does not. This changes the appearance dramatically.

My understanding is that, in everyday language, "frequent" means "often" but "regular" means a recurring event with equal spacing - says nothing about how often the event occurs. An event can be frequent but not regular, or regular but not frequent.

I've been considering going paperless at home for a while. I have a flatbed scanner which may not be the fastest solution, but my paper archive isn't too large and I don't mind spending the time. But what (Linux-friendly) software do people recommend for organising the PDF output? I'm imagining something like an email client - documents arranged by date, with a subject and sender field, etc. Searchable and sortable! Since my volume is low, manual input of this metadata would be acceptable. Any ideas?
