I have GS100 that was the first 'wide mode' cam from Pany I think.
In Cinema mode (found from the menu and not the direct button) the 4:3 is croped from up and down and apparently you use just the 4:3 part with reduced resolution (probably what any non 'wide' cam would do to simulate wide)
In wide/procinema mode the CCD area used is slightly widened and the vertical resolution reduced. This is even greater for the following models GS400, etc (wider part of the newer chips).

GS300 uses same size 1/6 inch CCDs so I suspect the implementation is almost same as GS100.
Notice that the pixels count (per CCD) is 800k but for video only 640k are used. For stils this changes to 700k so you can't rely on comparison with stills and video.
Now the Japanese pages for GS100 are gone and there were nice schems explaning the exact area and pixel cound of the CCDs used in the different modes.
Cheers, Bogdan

Edit: Here is copy from the GS300 specs (transformed from Japanese)

1/6'' CCDs
Total number: 800k×3、
Effective pixels:
Video: 640k×3（4:3）/540k×3（16:9）
Photo: 710k×3（4:3）/540k×3（16:9）

So may be you can compare Video to still in 16:9 as it seems it uses same area of the CCD!

Edit2: I forgot to mention and it is confirmed from the spec. This type of cams are not NATIVE wide - as you see there is resolution lost when using the wide mode.
