How to edit Quicktime MOV's info?

[yanzhigang4]

I brought a canon 600d DSLR, with 18-135 lens. But this lens has some terrible problem that shaked when focus.

In china, it has buyer protection rules that can return the goods if it has problem within 15 days.

I got the problem out of 15 days, so I have to change video date to May 3rd 2010.

I have MOV file in H264 code. info like this.
