I use Cyberlink Power

I use Cyberlink Power Director 14 which is good editing software and not too complicated. But unfortunately it does not produce interlaced video format. So am using Adobe Media Encoder CS4 to convert the M2TS final video to MOV Interlaced HD. However when I set the Encoder with Upper Field First for Interlacing, the final MOV HD file Scan Typ-e is PROGRESSIVE and not INTERLACED. I do not know why.
