DV100 Resizing

Hi,
Does theippiYCrCb422ToYCbCr422_10HalvesMB16x8_DV100_16s8u_P3C2R resize the width from 1280 to 1920? My final image is always 1280x1080. Is there a fast way to resize just the width? I find theippiResizeYUV422_8u_C2R function slow.
Any suggestions would be great.
Thanks.

Ok, thanks Paul. I tried that, it is faster but the cpu jumps to 80%. So then I tried #pragma omp parallel for on the YUV resize and same thing, 80% cpu but twice as fast? I have parallel amplifier but that did not give me any hints why this is happening... Does anyone have any thoughts? Could it be a cache problem? How do I detect cache misses?
