I haven't got the answer for your problem, but just wanted to mention: If you think the problem lies in the start of the scaler, you can turn on the runtime configuration for the cvi and configure it from your nios-core to start as the last component. There are control registers for the cvi (but I am using 9.1, don't know if they are added in that version). So perhaps give that a try. (Perhaps you even must not configure all registers of the CVI, do the configuration in the sopc-Builder and in the NIOS just try using IOWR(ALT_VIP_CTI_0_BASE, 0, 1) could get it running, perhaps. The benefit is, you can then read the fifo used words by reading at offset 3 I think, so you can easily see from the NIOS if you have got your overflow there)
