Newbie Question - What am I doing wrong?

Hey Tutorialized,

I'm new to this forum so sorry if i'm doing something wrong.

i'm not sure if people have the same problem, but I don't know the key words to searth it...

But my problem is that cinema 4d suddenly eats my first frames, like it has a max amount of frames that it can render. I have it with these render settings:

AVI - all the compressors
1920x1080
Frames 0 - 360, and it starts to happen around frame 130 and then it go's like this, 1-131, 2-132, 3-133.

And I have a nice i7, gtx 460 system.

Please help me, I'm stuck and again sorry if I'm posting a problem that is fixed allready
