Solution

The Video Scaler v3.0 Rev 2 patch fixes a problem in the constant mode when the number of taps is greater than 4, however it causes the pcore generation to fail.

This is resolved in the Video Scaler v4.0 and later.

If a users need to continue using the Video Scaler v3.0, then they should revert back to the Video Scaler v3.0 Rev1 patch.
