Problems with transitions and HD video from a Canon Powershot....

Question

Hello:
First of all thanks a lot for taking the time to look at the question.
I have recently bought a Canon PowerShot SX200 IS, mainly for photos but it can also record HD video.
The videos it makes are H.264, 1280 x 720, Millions
PCM lineal, 16 bit little-endian entero firmado, 1 canales, 44100 Hz and are .mov
I have a Mac Pro, 2.66 with 5GB of RAM and a NVIDIA GeForce 7300 GT 256MB videocard.
and finally my Final Cut is 6.0.6
__Ok, so here´s the problem:__
I can play the videos on Final Cut with no problem, it just has to render the music but when I want to use any dissolve it doesn´t work, well it doesn´t work with any transition at all between the same videos of the canon or with others formats.
To explain a little better I give you an example. I drag the cross dissolve to two different videos of the same camera and they don´t stick or sometimes it only sticks on one of them, but mainly it doesn´t stick.
Any ideas?
If you need more info please let me know.

*ohh, thanks Nick :)*
Now I get it, this solves so many question of failed transitions that I never realized over the years, hehe. +I know I say that it was the first time but with the answer I just get it that I had this problem before but I didn´t connect with this one :(+
Now it seems so obvious that I feel a little dumb but it´s better 15 minutes of stupidity that a whole life of it Well in my case it was like 4 years but it´s better than a life time, hehe.
Thank you all for thanking the time to answer my question.
