I don't know about the reading as we are not there yet.
DD2 would watch tv or dvd all day if we would let her. I have noticed it is much easier to have no tv time, than little. If she gets to watch 20min few times a week she keeps on asking it all the time. (I work fulltime so there is really no time for her to watch it everyday) When she keeps on asking (whining) for tv or dvd she has hard time concentrating on anything else, no playing, no puzzles, no books. It is much better that she has no tv time except on special occasion (long trips, mom and dad busy, being sick). Without tv she can entertain herself very well and seems to have much better time than being in front of tv
One Saturday we tried to see how much she will watch if she can decide. This is how it went: wake up, watch dvd, eat fast breakfast watch some more dvd, go out to play and when coming back watch some more dvd, eat lunch and go back to watch dvd, you'll get the trend.
I'm bit the same way (especially with computers) so I understand her very well. I read more books during the months we were out of internet than rest of the year!!!!! I hope someone would restrict my computer time so I would use my evenings more wisely LOL
