Does VIP core work with Quartus web edition or subscription edition??

The VIP cores will work with either the web or subscription edition of Quartus. You can evaluate the VIP cores in opencore plus evaluation (http://www.altera.com/literature/an/an320.pdf) mode without any license. With the hardware tethered to a PC, the cores will run indefinitely in evaluation mode and I think they will work for about an hour in untethered mode.

I have the altera open cores license but the problem is that, when i run the SOPC builder it builds without any errors, when i try to compile the design in quartus , it gets stuck at 4% and hangs. 

 I went back to the project folder and found out that the file that is generated for the Clocked Video Input( also all the remaining ip's of the VIP core), a vhd file saying GENERATION : DEFFERED
