Actually, the 640x360 is actually likely to be the native...
640 /
16 =
40, 360 /
40 =
9. The
16:
9 ratio is maintained.
With the one from your Olin STB...
720 /
16 =
45, 576 /
45 =
12.8... The
16:
9 ratio is not maintained.
So, what I think is happening is that STB's are upscaling the 640x360 video or, more likely, the video is transmitted from ABC as prescaled-up (dimesions required for PAL-TV standard transmissions in Oz.)
[edit: Note that the 512x288 also gives a 16:9 ratio - so again, either could be the original (or neither
)]
[edit2: It doesn't half get ugly after reading Wikipedia on the subject of
PAL,
576i, and
Anamorphic widescreen. Bleh!]
