I see no one has directly answered your question

The reason is simple, You are thinking like a computer user, RePlay
(And TiVo) are aimed at TELEVISION users, and the resolution they use
is standard Never Twice Same Color (ok, Ok, NTSC really means National
Television Standards Comittee) video, or 1/2 of it
