Interlacing doesn't scale, the pixels do. The line size doesn't change.

Whether or not the image blown up by 33% will look horrible, well, I'd
expect you'd see pixel artifacting, which might be considered horrible
looking.

The OP might also see a problem with field order, since DV is lower field
first, which can be fixed by raising or lowering the image by one line.

 regards,

 sb
