I hope to use a TiVo for 'playback skills training' with my tennis players during practice. My plan is to stream from the camcorder to the TiVo via HDMI or S-Video. All I want to do is pause, rewind, and slowmo the live buffer -- I don't want the TiVo to actually record anything. My goal is to have the players watch their stroke frame-by-frame using the remote control to jog the video. (A flat-screen TV will be hooked up to the TiVo). Do you think this setup will work, and if so, which model TiVo would be most suited to this task? Are there any potential problems I haven't thought of?
