pel said:"Technically speaking, yes, installing Magic Lantern will void your warranty. However since it is loaded on the fly and is stored on the CF card (it modifies nothing on your camera's system at all... As I said above it is best to think of it as something that is an 'overlay' to your camera's normal firmware), simply taking out the CF card and restarting your camera will return your camera to a state as though it had never had Magic Lantern on it. With this in mind, if you did have a warranty issue, essentially Canon would have no way of knowing whether or not you ever had Magic Lantern installed."
Taken from here
From personal experience, I'd say give it a whirl. I looked hard to find anyone with any issues having installed it, and found none. In fact, I've yet to come across someone saying that they don't like it.
Takes a bit of getting to grips with, but well worth the effort IMO.
bensambrook said:Yeah it will be installed on the SDHC card, a CF card is a compact flash which isn't used on the 550D model.
From what I gather, yes. With a simple reinstall of the original firmware.

Tbh, tho' I can't see you wanting to delete it. Updating upon new releases maybe, but NOT deleting it
Followed the instructions carefully regarding boot flag on SD card and latest Canon firmware etc.
The SD card has to be bootable. Storage devices can have various 'flags' set, one of which is 'boot'. ML needs to boot itself from the SD card to install. I'm sure there's one or more free utilities in Windows that does this, I use Linux and used gPartEd. Don't forget to RTFM, the points about formatting the card in camera and resetting all custom settings is likely to be important. You can re-do them after install. ML probably/maybe works if you don't but I didn't risk it.I watched the install video which looks simple, not sure what you mean about the above?
I have never heard of a ML firmware, looks interesting Whats the advantages for video?
