Buffer Overflow and Underflow in Clocked Video Input/Output

Hi Faisal,

I've had a hell of a time with the VIP suite and sopc builder, designs that worked in 9.0 would not run after I upgraded to 9.1 and the main reason was that I wasn't using TimeQuest to constrain my clocks and important video signals. I'm still learning, and I still have some issues, but I had a similar problem with under/overflows and flickering which were both corrected by timing constraints - have you constrained your design? There are also .sdc files in C:\altera\91sp1\ip\altera\clocked_video_input\lib (and \clocked_video_output) that you should add to the design files dialog in settings too if you have not already done this.

Also, is there a difference in your frame rates on the output and input video?
