SOPC Erro upon Generate

[Altera_Forum]

Good day. 

I am trying to "re-create" a sample/demonstration project from University Program called D5M_Video_In using DE-2 DevKit. The sample uses the SOPC version 9.1 but i am using the later version, 11.1. I did not have a problem determining the components. I just followed the settings of the components' parameters. I completed the components with the proper parameters in no time. However, the errors presented itself when I clicked on the "Generate" button. There are three components that produced errors.  First, video_decoder_0 which says: https://www.alteraforum.com/forum/attachment.php?attachmentid=6847

Second component: 

video_clipper_0  https://www.alteraforum.com/forum/attachment.php?attachmentid=6848   I tried editing the .vhd file but doesn't work. I think it re-generates the file and writes the same thing.

Third Component : video_dma_controller_0
