overflow in video input, how to make it work right?

Hi all 

I am using a de2board on which I am trying to make a video processing system. 

My actual problem is that I get an input overflow in cvi. 

I'd like to know HOW can i adjust that. 

I thought that I could use a bigger FIFO, or to speed up system clock, but I think ha ve not enough space on chip. 

I fear that the problem is about the sdram troughput that slows down the video pipeline. 

I am using an SDR SDRAM, 16 bits wide, 100Mhz max controller clock. 

Video system (ips) runs at 100Mhz too. 

any hint please?
