Thanks BugMaster and Simon,
Sorry for not replying sooner.

I tried changing the code to force all blocks to interlace, and encoding a
stream.
But one of acTVira TV sets couldn't decode the stream.

I suppose that the decoder read a 'mb_adaptive_frame_field_flag' in a
sequence parameter set.
So I try changing the code. In encoder/set.c:184 change the line to:
    sps->b_mb_adaptive_frame_field = 0; //param->b_interlaced;

Nevertheless, it still didn't work.

Thanks,
reshia
