no video playback with quicktime 7

[Guest]

I have the latest i-tunes installed 7.2,which had quicktime 7 bundled with
it,now i have no video playback just a black screen in the qktime player (mov
qktime files)but i have sound.I tried a complete format and re-install of
vista 32 bit,and reinstalled quicktime 7 to see if there was any conflicts
with previously installed software,but i still have a black screen in the
quicktime player window,again with sound only.Curiously an earlier version of
the standalone quicktime 7 worked ok albeit with vista aero disabled.I have
tried converting the mov. files to avi. and this has the same result ie black
video with sound,if i convert them to asf. files they work.This is not an
ideal solution as i have many mov. files and converting all of them will take
a lifetime.Has anyone else had this problem? or does anyone know how to fix
it? any help is appreciated.

Hi. Quicktime is great on an Apple but a bit too weird in Windows for
my taste. Something to look at is whether your files will play in
iTunes rather than Quicktime. It is the same software but QT looks
like it has been fronted by the iTunes interface (go figure!).

Browse to the folder, right click and see what the default prog is (QT
or iTunes) and then try to open it in the other one. In iTunes you
need to double click the window in the lower left hand panel to get
sizing options etc.
