            Are the above settings correct, or should something be changed
            and possibly why?
            What are really "W Ratio" and "H Ratio" vs "Aspect Ratio"?

    w/h ratio _seems_ like pixel aspect ratio. But I have not quite
    figured out if that works the way it should.

    .......and more


Another Set Format menu selection is the Presets submenu:
 >
-> selecting PAL here fills in the preset attributes DV Video (corresponds mine 
for SD DV above)

Frame rate: 25.000
Width:  720
Height: 576
W Ratio: 1.000
H Ratio: 1.000
Color model: RGBA-8 Bit
Aspect Ratio: 4.000 : 3.000 Interlace mode: Bottom field first

-> selecting 1080i here fills in the preset attributes for HDV(?) or full HD 
Video

Frame rate: 29.9700
Width:  1920
Height: 1080
W Ratio: 2.6667
H Ratio: 1.8750
Color model: RGBA-8 Bit
Aspect Ratio: 16.0000 : 9.0000 Interlace mode: Bottom field first

......
Third, I notice the changed values W.Ratio=2.6667 and H.Ratio=1.8750
Again, what are and what do these W and H ratios .......?

Playing with number ratios, look at this:

Width of 1080_HD_video/DV=1920/720 =2.6667=W_Ratio_for_1080_HD_video
Height of 1080_HD_video/DV=1080/576=1.8750=H_Ratio_for_1080_HD_video

Mere chanches or some reasonable explanation for these coincidences?
