who has a canon 550d here and uses movie mode?

im only learning still and got one today. I wanted to replace my hanycam which is great outside but grainy in the inside light.

The canon seems to be grainy also when i did a test tonight. It was inside and under fluro lighting which is decent enough for normal reading. i still need to play around a bit but can you achieve decent video quality on it at night?

Cheers.
