Hi Sims,

Besides my previous tip, here's another... 

My quicktime app is never installed in C:\program files....!!!

To find where, look first at...

And there's another key that's interesting for you - but it's not reliable 
(no xvid or divx which i have installed)
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\QuickTime.aif  -- the AIF is the 
interesting bit which are the file types QT handles...

And there's a key in the registry that gives you also the installed 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
but with this last one, unfortunately, you can't list the subkeys in a 
registry branch...

And i couldn't find any utility that could list the existing codecs. GSpot 
(free) tells you if you have the codec or not or what codec you need to 
play a file
but it's not exactly script friendly... I'll see if i find a vbs trick
