What would you do with HD video on a 480x320 screen?
Anyway, it'd need an extra chip to work, which would make the phone bigger, and then it'd kill your battery when you used it (receiving signal, decoding video, playing sound and keeping the screen lit), so it would be useless in all but a few scenarios, like riding the bus to work (but is there anything worthwhile on at that time...).
I used to have a TV-tuner for my Game Gear. Used it maybe three times. It's a useless gimmick 95% of the time.
