Do any of you Canon Ixus owners know if the auto-shutdown can be over-ridden?

The Ixus i does allow you to turn off the power save feature, however it doesn't appear that you can stop the display turning itself off. The max time is 3 minutes.

It weighs 125g and supports PAL output, but I'm not sure about the frame rate. Cheapest I've seen it is at ebuyer.com for £150 ex VAT, but it is more than worth that considering it's a 4 megapixel camera.
