I am new to Tivo. Why do recordings start over from the beginning every time you go back to them? I am used to recording multiple NFL games simultaneously, and then switching back in forth between them. For example, I will watch one until I catch up with the live action, and then switch to the other until I catch up with the live action, and then return to the first game. I have always done that with both cable and satellite DVRs. But Tivo doesn't pick up where I left off on recorded games, instead it starts the game over each time I go back to it. My question is: AM I not doing it right, or is this a design flaw with TiVo DVR technology?
