VIDEO -- modes=flashhigh / flashstd and default_modename.mp4

[M2]

Hi,

have just tried --multimode to record b00rrd81 (Human Planet - E1) to 
see the quality difference
and noticed that flashhigh (335MB) and flashstd (202MB) are same screen 
resolution 640 x 360 / Audio but different in size.

VLC player is reporting in Codec Information (CTRL+J) same information, 
so I am puzzled.

Does anyone know?

So far I have managed to colate this info about video files:
--modes=flashhd - H.264    1280 x 720 1704 kbps     AAC+ 240 kbps xx00 kbps
--modes=flashvhigh - H.264    832 x 468    1404 kbps     AAC+ 96 kbps 
1500 kbps
--modes=flashhigh - H.264    640 x 360    704 kbps         AAC+  96 kbps 
800 kbps
--modes=flashstd - H.264    640 x 360    704 kbps         AAC+  96 kbps 
800 kbps
--modes=flashlow - H.264    400 x 224


As well as is there any way that when I do not use --multimode at the 
end of the file I have for flashhigh
Human_Planet_-_1._Oceans_-_Into_the_Blue_b00rrd81_default_flashhigh.mp4

insted of just

Human_Planet_-_1._Oceans_-_Into_the_Blue_b00rrd81_default.mp4

Thanx in advance.
