Many thanks for this info. Interestingly, the article you referenced has the following section:
"
While non-drop timecode is displayed with colons separating the digit pairs—"HH:MM:SS:FF"—drop frame is usually represented with a semi-colon ( or period (.) as the divider between all the digit pairs—"HH;MM;SS;FF", "HH.MM.SS.FF"—or just between the seconds and frames—"HH:MM:SS;FF" or "HH:MM:SS.FF". The period is usually used on VTRs and other devices that don't have the ability to display a semi-colon."
From a design perspective, I'm surprised anyone would use a semicolon when a period (.) is available. With increasingly sophisticated graphics often shrunk into smaller spaces, noise is the enemy of functionality. Every redundant pixel should be removed. I'd recommend to Cyberlink that the next version of PowerDirector switch to periods from semicolons.
BTW, cool icon (and well designed). CF-104 Starfighter?
I've never figured out why my icon looks like crap on some websites (this one, for example).
