Yes, I have uploaded a sample file coded with 100/1 and the other with 10/1.

They are both coded using the same program and parameters, a frame each
100ms.

http://www.alu.ua.es/j/jma27/out_bad.ogg

And I'm using this parameters
    ti.width=320;
    ti.height=240;
    ti.frame_width=320;
    ti.frame_height=240;
    ti.offset_x=0;
    ti.offset_y=0;
    ti.fps_numerator=100000000;
    ti.fps_denominator=1000000;
    ti.aspect_numerator=1;
    ti.aspect_denominator=1;
    ti.colorspace=OC_CS_UNSPECIFIED;
    ti.pixelformat=OC_PF_420;
    ti.target_bitrate=0;
    ti.quality=5;

    ti.dropframes_p=0;
    ti.quick_p=1;
    ti.keyframe_auto_p=1;
    ti.keyframe_frequency=64;
    ti.keyframe_frequency_force=64;
    ti.keyframe_data_target_bitrate=0;
    ti.keyframe_auto_threshold=80;
    ti.keyframe_mindistance=8;
    ti.noise_sensitivity=1;
