Series 2 (except for dual tuner models which are for cable only), requires the digital converter box to receive antenna, and the tivo controls it to change channels. Your HDTV does not have a digital to analog converter, to be specific, it has a ATSC tuner which receives the digital TV, so it does not need any converting to show video. Older TVs and the Series 2 has a NTSC tuner which was for analog channels.
S2 records only in analog and that requires the converter box, but only selected converter boxes will work properly, listed on the tivo.com site.
Although, getting a converter box will work, the picture quality is not. Analog was not meant for HiDef quality. Picture will appear to be grainy. Cost of a converter box is less then the cost for a new tivo, but a new Series 3/HD/ premiere will have HiDef quality and record 2 channels at once on antenna and/or cable.
