When I am shooting in live-view, it is particularly frustrating how fast the display clicks of to conserve battery. Can I increase the time before it does this?

This question might be a little bit off topic, but I figured I would ask anyway.

This is something that is usually covered in the manual. Maybe have a look there to find the answer. – Gregor Müllegger Sep 14 '10 at 11:15
In 500D it's "auto power-off time" in the menus, by default 30 sec. It isn't specific to the live view, but it also controls the frustrating feature that you described. – Jukka Suomela Sep 14 '10 at 17:39
@Gregmuellegger I looked pretty seriously through the manual and could not find it. – BBischof Sep 14 '10 at 20:11
@Jukka you should add that as an answer, to earn the reputation from having the right answer :) – Rowland Shaw Sep 14 '10 at 20:18

Jukka is correct, you can solve the problem by changing "auto power off" in the 450D settings menu (first yellow spanner icon).

The only thing I have to add is that even when auto power off is disabled, live view will still stop after 30 minutes to avoid overheating the sensor.

My 450D seem to turn off Live View at varying intervals. I am not certain why, however it seems to depend on the various exposure settings, primarily ISO. I am guessing it is adaptively trying to prevent any damage to to its probably capped at 30 minutes, but primarily based on some kind of temperature sensor. – jrista Sep 15 '10 at 3:42
