ttp:* test files

Here's a set of test files that I hope covers most of the parameter 
attributes.

I have a few questions:

a) As I'm not familiar with 29.97 and drop frame, etc., could someone 
look over the frameRateMultiplier and smpteMode files to make sure my 
interpretation is correct? For the latter test, I've used Glenn's 
timecode values from the spec which highlight the difference between 
drop and non-drop frame, but a longer duration of visible text would be 
better (i.e. > 3 frames). Does anyone have a drop-frame timecode 
calculator, so I don't need to work it out frame-by-frame?

b) how can we test ttp:pixelAspectRatio ?

c) how can we test ttp:profile ?
