Last Modified: 2013-12-08
Last night I could watch Quicktime movies (learning Photoshop via  today, when I start a movie, the Black Quicktime screen shows for 1 second then qoes white and nothing happens.  I have changed security settings but they still do not play.  I have also done a download and repair to no avail.

I cant attach a  picture of the message at the bottom of the screen so here goes some sloppy typing to show you:

Javascript:viewedMovie(312,'cl-m2'{62e96ccc-32a7-4774-814d-dfeb3485f50d},'no',flase,880,676,16940)   whew!

anyway, hope that typed message helps

Are the file types all .MOV  extensions?  Have you checked which Player is trying to control that movie type?  Are you current with Updates?

The files trying to play in Qtime all come from  They let you preview some of the files to see if you like there tutorials (which btw are excellent).  I see you like to embleshish your family memorys and I use to learn Photoshop CS2 and CS3 and for that matter Photoshop Elements (I got em all).

I believe they are all mov files.  Something has changed on my system since yesterday (when I could play them).  I did a restore to yesterday at 1130 am and that did not work.  I should have probably goned back farther (and I still can, except for the fact I have been changing things to correct other problems) including uninstall and reinstall IE7.

BTW, you have 40 years, I have 38 (started in IT in 69, but now out of it and doing other things.) Nice to find someone older than me ha ha


I ran Windows Explorer for file types, and saw MOV files were quicktime movie (the app that ran them)

Regardless of our age, we're all kind of the same in terms of dynamic environments.  It seems the more we learn in these excitingly changing times, the more we find to learn  Great stuff, keeps our brains guessing and working, lol!

I noticed that the site has Flash enabled links, so would encourage you to try adding Player updates, for starters, and again, clearing cache, and adding that link after installing players and closing/rebooting IE to test, to your Privacy Tab in IE to allow it.  From Tools - internet options - privacy.  If unclear, will check back later this day.

Good point; on this system, running XP SP2 with IE 7.  Not yet choosing to move to Vista Ultimate, but eventually.

These Troubleshooting links for Quicktime are useful.

Before logging off, found one other similar issue and fix here:
Open Quicktime 7
Click on Edit tab and go to preference,
then click on Quicktime Preference.
One that opens click on Advanced tab
You will see a selection for video or direct X.
Click on Safe mode (GDI only)
Then click on Apply, then OK.
Restart Quicktime and play a movie to test.
