Quicktime version 7.1.3 for Mac cannot play AVI file

The AVI file actually "plays" as in, the bar moves, but there is just a white screen, and no sound. I have checked the movie info and it shows that the format is ", 640 x 360, Thousands MPEG Layer 3, Stereo, 44.100 kHz". I have totally no idea what that means, and why the file cannot play. It plays perfectly well on a Windows computer which shows that the file is not corrupted.
I have also followed the suggestion made in one of the earlier discussions and downloaded Perian. However, when I clicked on the "AppleIntermediateCodec.component" file, I only got a message that says "Error Opening Movie: The movie cannot be opened." So, Perian seems to be another dead-end for me.
Incidentally, I have also tried playing the AVI file with Windows Media Player for Mac. The message is that the file format is invalid.
Any suggestions as to how I can coax my Mac to play the AVI file?

The codec info should have been listed before the comma that precedes 640x360. Seems to be a bug in the recent versions of QT 7. If you have QT Pro you can still find the codec name by opening Movie Properties and checking the video format that way. Anyway, since Perian cant play it I suspect you are out of luck in MacOS x. Not all avi decompressors have been ported to OS X. It may be that the compressor is one of the old Indeo codecs and those definitely will not work in X. They will work in the Classic environment but a lot of you folks have given up on Classic. Just in case here is a link to the Indeo codecs for Classic: Indeo codecs for Classic
Have you tried playing it in VLC. If it is not an Indeo file VLC may play it.
The Mac version of WMP doesn't play avi or mpeg files -- mostly it plays wmv or asf files and not even the most recent versions of those formats.

What is the URL from which I can download Firefox 10 for Mac?

I cannot use Firefox 11 for Mac because it does not yet support a security add-on that I require. So I want to downgrade to Firefox 10 for Mac in both the 32-bit and 64-bit versions.
However, I have been unable to find the URL from which I can download these two versions of Firefox 10 for Mac. Yes, I tried putting various keywords into the search box: "download" "Firefox" "previous versions" "downgrade" etc. Still I couldn't locate the URL.
Would you be so kind as to send me the URL?

Just replying to help keep track of the thread. I have been looking also. I can find where to load version 3.6 - but not 10.0.2
We are having printing problems with 11 that we never had with 10 :-(

Does the regular Firefox 8 release version work or does the version crash as well?

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Firefox desktop for mac does not save history

Using firefox desktop for mac. Recently it stopped saving my history. Forward and back buttons still work, typing something in the address window will make it pull up places I've visited in the past, but only ones I visited two or three weeks ago. Nothing recent. "Show all history" brings up the window, but there is nothing in it."
Private browsing is not enabled. I have enabled "remember my browsing and download history."
Another answer suggested I might have an anti virus or something that is disabling history. I looked, but I don't have anything doing that. Safari and Chrome are both saving their histories normally.
Any help would be appreciated. Thanks.

Elements 10 for MAC cannot print 8x10 on Canon mp970?

Elements 10 for MAC cannot print 8x10 photos on a Canon MP970 printer . I get a box that says can only print at 220 resolution. What should I do?

That's not quite what it's saying. It's tell you that at the physical size you chose (presumably 8 x10) your photo has fewer than 220 pixels per inch. So you can print 8 x 10 but the quality may not be first rate, since the original image just doesn't have enough pixels in it to print at that size with more pixel density.

Why does Firefox 4 for mac crash when attempting to manage add-ons?

Downloaded firefox 4 for mac yesterday. Working fine until I started adding add-ons/extensions. Since then, any attempt to manage add-ons or extensions crashes Firefox and requires a force quit.
Help?

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
Delete the files extensions.* (extensions.sqlite, extensions.rdf, extensions.cache, extensions.ini) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar to do a compatibility check.

Since upgrading to Lion, I cannot play QuickTime videos in Safari 5.1.1, not even on Apple's own website?

Upgraded to Lion and now I cannot watch QuickTime videos in Safari 5.1. Did not have this problem in Snow Leopard. QuickTime videos do play in Firefox. I cannot even play QuickTime videos on Apple's own website. Any suggestions? I'm using a Macbook Core 2 Duo.

Hi Sami,
I have partially solved my problem. I had software installed for a Twelve South BassJump (it improves the sound of your laptop speakers). When I removed that software, I was able to play videos on Apple's website in Safari. The company has beta software available from their website that is supposed to be Lion compatible but when I installed that the problem returned. But even with that software removed I still cannot watch videos on some sites such as Other World Computing.
I just got a new Macbook Pro yesterday with Lion installed from Apple and all video plays fine. So I believe there must be some compatibilty issues with some plug-in. I have Perian and Flip4Mac installed. I removed 3ivx and the problem still remains. I've read conflicting opinions as to Perian being Lion compatible.
Everything works fine in Firefox at this point so at least I have that to fall back on.
Check your system preference pane under "other" and tell me if you have any of the plug-ins I mentioned installed. Maybe we will be able to see a common culprit.
Let's keep each other posted.
Thanks,
Chris in Ohio (USA)

Quicktime don't play quicktime content on the internet.

I just updated to 10.5 and now I can't play any quicktime content on the internet. I can play the quicktime movies on my computer but I can't play it in any web browser. What is up. How do I install the plug-in if thats what is wrong.

These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
It is known to work in the great majority of cases with Safari 3.0.4, QT 7.3 and OS 10.4.11. (If you are running Leopard, ensure that all plug-ins have been updated for OS 10.5)
Assuming you already run Tiger versions OS 10.4.9 or above (this has not yet been verified with Leopard) and have Quicktime 7.2 or above, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer 10 for Mac from http://forms.real.com/real/player/blackjack.html?platform2=Mac%20OS%20X&product= RealPlayer%2010&proc=g3&lang=&show_list=0&src=macjack
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
Adobe FlashPlayer should first be uninstalled using the appropriate uninstaller available here: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=2 and then the latest version obtained from here: http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash and installed.
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.)
In earlier versions than QT 7.1.3 in Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
You should also ensure, if you are running Tiger 10.4.11 or Leopard, that you have downloaded and installed the correct version for your Mac of Security Update 2007-009, which also deals with the Quicktime/Flash issues you may have experienced, such as the '?'. What happened was that both Quicktime as well as Adobe FlashPlayer tried to play the Flash video at the same time. This no longer happens. (N.B. Security Update 2007-009 requires both a restart and a permission repair.)
See also the very informative post from QuickTimeKirk dated Dec 3, 2007 in this thread: http://discussions.apple.com/thread.jspa?threadID=1268489&tstart=0
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them).
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz.
Important: Now repair permissions and restart.
You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.

Cannot play Flash content in IE7

When I navigate IE7 to any site (including adobe.com) that
has Flash content, I get a message saying I need to enable
javascript (it is) and/or upgrade my Flash player. I am running
Vista, and this worked until sometime in the last week or so.
Flash content does run on this machine inside Firefox 3.0.1,
but IE7 appears to be dead.
The error message I get is "Error in loading DLL". It appears
to pop up when the javascript code is trying to load or access the
flash content.
I tried installing the Flash Player 9.0.124 using the web
site - no luck.
I tried uninstalling (clean), rebooting, then installing from
the web site - no luck.
I tried uninstalling (clean), rebooting, then used the manual
installer (Install Flash Player 9 AX) - no luck.
I tried uninstalling (clean), rebooting, then used the manual
installer (FlashUtil9f) - no luck.
I tried running reset_minimal.cmd (per instructions) - no
luck.
I tried disabling my AV (Kaspersky) while repeating all of
the above - no luck.
I tried running sfc /scannow but it reports no errors.
I tried the Tools/Internet Options/Advanced/Reset to "reset"
IE to its defaults - no luck.
I am really, really stumped on this one. What should I do
next?

BWolfe, dougclutter, and others with Doug's problem:
BWolfe, I'm truly amazed that dougclutter and others have had
this very specific and real problem for so long, and Adobe hasn't
lifted a finger to cure it. I'm stunned. I've been plagued with
this thing for at least 3 months now, and have been all over the
net looking for a remedy, after finding absolutely no help from
Adobe.
Here's what my symptoms are:
IE with Flash works in all accounts but mine.
Latest Adobe Flash player (10) is properly installed. Flash
content will play on IE8 in anyone's User Account on this machine
but mine. The only way flash content will play in my user account
is if it is started as "Run As Administrator". Can actually run 2
instances of IE side by side, one started normally, the other
started as "Run as Administrator". Oprah, U Tube, etc., will run
flash content in the latter window, but won't in the former. Flash
errors (in IE7} are something to the effect, "Can't run DLL", with
line number reference, etc. No help from Adobe, HP (my machine
manufacturer) or Microsoft without paying them a bundle. Just
updated IE7 to 8, problem unchanged.
Elaboratiing:
When right clicking on where Flash Player is supposed to be,
then clicking the "about Adobe Flash... ", the browser is sent to:
http://www.adobe.com/products/flash/about/
When clicking on the error message at the bottom of the
browser, the following error message is displayed. (This was
copied, which Vista gives you the opportunity to do, then pasted
here.)

Message: Error in loading DLL

Flash content DOES play with Adobe Flash 10 in my user
account with Apple Safari browser when started normally, just not
with IE8 browser. However, the IE8 browser does play Flash content
in any and every other user account.
BWolfe, instead of telling us about proper Adobe procedures
for reporting and troubleshooting these things, how about you
forward this to someone who can tell us how to fix this thing! I,
like dougclutter and others, have been thru the entire Adobe Flash
Player troubleshooting guide, carried out every suggestion there
exactly, to no avail. I can show you at least 3 other instances of
different folks with this same problem. And, as I think I've seen
elsewhere in this thread, and tried myself, Adobe certainly doesn't
make it easy to report non-paying customer problems, as with Flash
Player.
It's high time Adobe gets with at least one of us to help
diagnose and cure this problem, and then adds the info to their
troubleshooting guide, or else fix it in the application if
possible. Whether the problem is in the app, or do to interaction
with Vista and possibly XP, you guys need to look into this thing.
I, for one, would be more than happy to help you 'shoot this thing,
I am and engineer and have been computing since the DOS days.
Bewildered,
Dave
