[mpeg2] Why is horizontal res. set to 704?

[Marcel van der Boom]

When I was looking at the code in kfir.c I saw in function

static int Kfir_DownLoadParams(struct kfir_dev *kfir)

.
.
.
switch (Params->KF_HorResolution) {
        case KFIR_H_160:
                mbWidth = 160 / 16;
                break;
        case KFIR_H_320:
                mbWidth = 320 / 16;
                break;
        case KFIR_H_352:
                mbWidth = 352 / 16;
                break;
        case KFIR_H_480:
                mbWidth = 480 / 16;
                break;
        case KFIR_H_544:
                mbWidth = 544 / 16;
                break;
        case KFIR_H_640:
                mbWidth = 640 / 16;
                break;
        default:
        case KFIR_H_FD1:
===>> 
        mbWidth = 704 / 16;
                break;

==
Why is the full D1 case horizontal width set to 704 (like 720 minus 16 ?) and 
not to 720? There must be a reason for this.


The same question applies to the 352 width case instead of 360.

Can someone elaborate on this. Is the spec sheet wrong?

Thanks,
