Sad, but true...

Well, i wouldn't call this an "official" summary, but just my  
experiences...

What can (probably! test test test test!!!) be displayed on Win without  
QT:

Sound:
WAV, AIF, AU, MP3

Video:
AVI (even DivX, since AVI, like MOV, is just a container for different  
codecs etc...)
and MPG


NO midi and NONE of the win streaming formats like WMA etc...

I have successfully used the above mentioned filetypes on win without  
QT,
just with player-objects...

Still there were some surprises like WAV sounds which could be played  
in the WMP
as well as QT, no fancy codec, but it just does not want to play in  
RR...

And one MPG file was reported to always play at 0,0 of the card, big  
fun...
Although i could not reproduce this, i think thats true... ;-)
See line 1 ;-)

The controller is nice but also a QT only feature, yes...

Check this old stack of mine for a custom controller that will work  
with/-out QT:

Custom Controller for Players v1.0

You find it on:
http://www.runrev.com/Revolution1/developercentral/ 
usercontributions.html

waaaaaaay down the page :-)

Sorry, no idea...

Easy to create your own...

A simple "scalebar" (o to 100) with a simple script:

on scrollbardrag curr_value
    set the playloudness of player x to curr_value
end scrollbardrag

might do...

True...

I hope this makes things a BIT clearer...

Again, test, test, test, test...
And test...!
