Problem with Altera Video Input Daughtercard (DC-VIDEO-TVP5146N)

Hello,
Does somebody work with DC-VIDEO-TVP5146N Altera kit (http://www.altera.com/products/devkits/altera/kit-daughtercard.html) ?

I try to connect DC-VIDEO-TVP5146N to DK-NIOS-2S60N (http://www.altera.com/products/devkits/altera/kit-niosii-2S60.html) via SantaCruz interface. In fact I use NIOS with OpenCores i2c master to connect to TVP5146 video adc via i2c interface.

The problem is that all samples, that I’ve found for DC-VIDEO-TVP5146N, are specialized for CycloneII dev boards and isn’t open source.
When I test my system (StartixII + NIOS II + OpenCores i2c master <- i2c -> TVP5146) with SignalTap, it looks like TVP5146 doesn’t answer on my requests and in fact I can’t write and read any TVP5146 registers.

Have somebody successful experience with DC-VIDEO-TVP5146N ?
Thank you,
Alexander Petrov
