Converted .wmv to .mov will no longer play in quicktime

I have converted .wmv to .mov using the quicktime 7.6.4 save as feature and saved them to an external WD hard drive. They have been playing fine for months until yesterday, now i have a black quicktime screen, no sound or audio as the file plays, all that I have changed recently is that i have updated Flip4mac from 2.3.3.2 to 2.3.3.3 and updated Safari to version 4.1. I have run an Onyx maintenance scrypt and disc utility to try a repair a possible permissions or disc error, still no luck. I read an article on the Flip4mac site that suggested I export the file in quicktime, this has not worked. When viewing the files info it states the files codecs are windows media audio 9 standard*, windows media video 9 standard". After reading some other posts I installed Perian, but still no luck. If anyone can help to get these movie files operational again please advise.

I got an answer on the macformat forum that works, refer the attached link

Here is a crazy problem. My home movie will no longer play in iTunes.

I created a home movie using Final Cut Pro X. I shared it to ITunes. The video played ok. I then changed the name of the video under the "get info" tab in iTunes, and the thumbnail view of the video changed from the first frame of the movie to a picture of a film reel and the movie will no longer play. I tried changing the name back to the original, shutting down iTunes and the computer itself, copying the movie, all to no avail. I also tried accessing the movie from the finder, and it would not open using QuickTime or VLC. Any ideas?

The lack of a purchase date, although I am not quite sure why it happens, does not in itself prevent the track from being authorized and played. However, since the account name is correct and they have disappeared from your purchase history, something may have been corrupted.
Unless someone here has a better idea, you should take it up with iTunes Customer Service.

HT204370 Existing movie will no longer play on iTunes

I have on my iMac a movie (protected MPEG-4 video file, purchased from the iTunes Store in 2008) which was a present to me. The email address (hence Apple ID) of its original buyer is no longer active, and its companion password is unknown.
When I try to play this movie, I get the message that my computer is not authorized to play this movie, asking me to authorize it. It provides the Apple ID at the time this movie was purchased (“xxxxxxx”@hotmail.com) and asks for a password. Attempts to authorize by entering a likely password has no success. Attempts by entering my own current Apple ID and password bring up the message “this computer is already authorized” along with a black window. Clicking on this window brings up the usual play/stop/volume control bar at its bottom, indicating 0:00 status of play, with the double bar option (for stopping the play) offered, but the movie is not playing. Clicking on the double right triangle has no effect. Clicking on the single right triangle brings up the next movie in my collection.
I was able to play this movie a couple of OS upgrades back, but no longer with my OS 10.9.1. How can I access my movie now?

You will need to authorise the account that it's linked to. Was the film gifted to you (in which case you should be able to get your password for the account reset : http://iforgot.apple.com), or did somebody else use their account to buy and download it ?

All my downloaded(digital copy) movies will no longer play in itunes, i get a black screen, and no sound, but the time keeps going. how can i fix this?

All my downloaded (digital copies from dvds) won't play in itunes. I get a black screen and no sound, but the time keeps moving. How do i fix this?

Hi 22chill,
I recommend that we delete and re-download the movie from your purchase history:
Downloading past purchases from the App Store, iBookstore, and iTunes Store

When I import audio and move it into my timeline the project will no longer play?

When I import audio and move it into my timeline the project will no longer play?

The audio is a .wav file created in Audacity.
The OS is Windows XP
The verison is CS4
I have included images of the Sequence settings and the playback settings because I was not sure what information you would need.
I am not sure what you mean by waiting for the Audio to conform but I know I have imported the audio and gone back the next day and tried to place it in the timeline and it still did not work.

Video will no longer play, cannot add video content either.

Since this afternoon, iTunes video will no longer play. Not movies, not TV shows. I checked and music and podcasts still play. I thought it might be a conflict between purchased video vs video I added from my DVDs, but no such luck. Purchased content will not play. Nor can I add any new video, whereas I added a new TV show episode this morning.
If I go into the iTunes LIbrary file and select a video and choose "Play with Quicktime" the video plays just fine. But if I select "Play with iTunes" nothing happens. At all. Not even an error code. It's like I didn't select anything. If I try to add content by the keystroke "command O" and choose the file … again, nothing. No error. Just no response at all. When I open that file on my computer, select "Play with Quicktime", then choose "Share with iTunes" inside Quicktime I do finally get an error. "This file cannot be shared (error 206)". I looked up this error code and found this: "The filename or extension is too long." This does not make sense. The file names are fine and the extensions are exactly what I always use to add content to iTunes.
So it's like the entire video portion of iTunes has ceased to function. Any clues?
iTunes 10.4.1
OS 10.6.3

There are a g-zillion posts sharing your problem... but still no answer from Apple. The odd thing is that it is not affecting all of us.
I share your problem and it's doing my head in... if somebody mentions the 5 bloody R's again...!!!
Before updating to 1.2, ask yourself... how bad do you you really want Tetris????

Lots of my music will no longer play after latest update

Hello,
I have a lot of music that will no longer play in my iTunes after the last update. it doesnt happen with all my music, but a lot of it, and as far as i can tell, movies and tv shows are still good. when i click on the song, it just skips forward over a lot of songs that it cant play until it gets to the next one that it can play. to make things stranger, i synced my iPad to my iTunes, and the ones that cant play in my iTunes will play on my iPad. when i try to open the song using QuickTime player, i get the following error: error -2002 a bad public movie atom was found in the movie
what is a bad movie atom and why am i getting the error when trying to play an audio file, and why wont they play in my iTunes but will on my iPad.
System: Win7 Ultimate 64bit AMD A10 8GB RAM
iTunes : 11.4.0.18
QuickTime : 7.7.5
any ideas?
thanks

The contacts is saved on Google or Backup Assistance (Whichever you are using) and you can use ES File Explorer like I posted at http://community.vzw.com/t5/Android-Apps/Simple-way-to-Backup-apps-for-Hard-Reset/td-p/658707 , so you really wont loose anything but apps data...
BUT, I am not saying that you do this if that is your only issue... I was just pointing out that this is a good ideal to do with any Major Updates..
If the contacts isnt linked again you should get the option to link them again once the OS boots, normally it checks and then prompt to link again..

Adobe Premiere Pro CC will no longer play program after weeks of editing it

Adobe Premiere Pro CC will not longer play my program when hitting the play arrow. The first time I hit it will play. But if I stop and then hit play again it just basically hangs up. I've been editing this program for several weeks in Windows 8.1 with over 1TB of free disk space. It would occasionally not play but if I restarted the program it would go again and I continued on. However, now it has the problem on this program all the time.      Basically I'm not able to put the finishing touches on my program and have not been able to use Adobe Premier Pro for several weeks now.   I'm basically paying a 1 year subscription for a program that is not working correctly. WHAT IS ADOBE DOING TO FIX THIS PROBLEM?   I see that there are countless people having this issue on the web, so I figure ADOBE is aware of this problem.    IS THERE A NEW RELEASE TO COVER IT? IF NOT WHEN WILL THERE BE A RELEASE TO ADDRESS THIS ISSUE?
If I start a new program it seems to work ok... but I probably have over 100 hours into the current program... starting over from scratch would not be good.. and what guarantee would there be that the problem would not occur again after another 100 hours was invested into it?

Thanks for the suggestion, I will give that a try.   It didn't work to go back a few weeks on the first try. As I get a chance I will try more saves that are further back.
Adobe Premiere Pro is working for me for the new music video project I'm working on today.
It's just this other program is large. 1/2 hour length.   If I push play it will work the first time. Then after I stop, and move the cursor to another spot, as long as I wait 2 or 3 minutes for it churn away and update the monitor, then it will play again.    As long as I wait 2 or 3 minutes each time it won't crash.   If I don't wait and start pushing multiple play and stop requests it will crash.   My machine has 12G of memory and 1Tb free disk space, and runs at burst speeds above 4GHz.
Several weeks ago I also had this problem.   I deleted all the render files and rebuilt them, and after that it worked for quite a while. This time I've tried that twice and it didn't help.
Maybe it has something to do with the order in which I render the sequences?    I might try that again, and experiment with the order of rendering.

Quicktime 7.2 will no longer play specfic mp4 files

Quicktime 7.2 will no longer play specfic mp4 files that 7.1 and earlier versions play fine, But new mac running 10.4.10 will not let me install earlier version, these files where used and edited fine on similar spec mac running 10.4.9 (both intel)

You did nothing wrong!
Quicktime has never played wmv files natively. You ned to download and install Flip4Mac WMV Player from http://www.telestream.net/flip4mac-wmv/overview.htm (Windows Media Player for the Mac is no longer supported, even by Microsoft)

I have similar problem, my apple tv which has always worked properly with my Samsung tv will no longer play any audio after the latest 5.1 upgrade. Very frustrating as it was working perfectly before. I am starting to not trust apple upgrades until proven for example ios6 on iPhone with that stupid map app instead of google maps.
I just want to buy and hear my iTunes music and videos on my apple tv, could before cant now. Thank you apple. Time to pack up the apple tv and start torrenting without the ios-bs.
Disheartened apple fan.

Welcome to the  discussion forums.
Try going to synching in the sources menu on your tv and selecting 'change itunes library', when it gives you the passcode check itunes to see if the tv is showing up as a new device, if so try entering the pass code. It may be that your tv is seeing itunes as a different library because of a recent upgrade.

How can I import a movie into iMovie 09 from a hard drive? The movie will open and play in idvd but breaks into separate files that can't be downloaded when I try to import. Can it be done?

How can I import a movie into iMovie 09 from a hard drive? The movie will open and play in idvd but breaks into separate files that can't be downloaded when I try to import. Can it be done? I am trying to create a disc of player highlights for a collegiate coach, and I am using movie files downloaded to my hard drive from a DVD created on a PC.

No unfortunately it won't open in quicktime either. It does the same thing that Imovie does, separates it into two file folders audio and video, and if i select video it opens to reveal 8 files that cannot be selected. VIDEO_TS.BUP, VIDEO_TS.IFO, VIDEO_TS.VOB,VTS_01_0.BUP, VTS_01_0.IFO, VTS_01_1.VOB, VTS_01_2.VB, VTS_01_3.VOB. All of which cannot be opened or selected.
Opening it in Idvd and folllowing your suggestion works and I get a format code of NTSC. Is that the same? Thank you for your time and response.

About 1/3 of my 4100 tunes will no longer play. Please help!

Over the past year I have spent countless hours painstakingly adding appropriate track information, cover art etc. I like the tracks to be attached to the original album, not a best of. I also have a lot of extended versions, remixes etc which then have to be attached to the specific 12" or cd-maxi single etc and a lot of hard to find - hard to attach stuff. Needless to say - I don't want to do it again.
Anyway - I just noticed that a large quantity of tunes (looks like about 1/3 of the library) will no longer play. Double click on them and nothing happens. No cover art - it's as if the song is not there. A look at the "get info" shows the track in the right place with everything pointing to where it should be ... but no play. To add insult to injury, I can't get them back by double clicking on the track itself in Explorer. It still will not play. And these songs are not corrupt. I have been playing them for some time now without issue. How can I save my library and information and get these tracks to play again.
Side note: this has happened before, usually after an iTunes update and typically with only a few tracks, never this widespread.
Please help!

I have made it a standard practice to keep a copy of all music files - tracks under the Album -- at a separate folder location.
Do you have such a back up location of your music tracks? If you do, I'd suggest to try this:
Delete all tracks, that are NOT playing, belonging to one Album in iTunes. Then locate the folder in your backup location where this Album's tracks are located, and ADD this folder to iTunes. Then check to see if these play OK.
If they do, then repeat the process for all the rest.

Help please: iTunes will no longer play downloaded songs

ITunes will no longer play songs that I've downloaded from the iTunes Music Store. It used to play them, but now it won't play them at all. It will play only songs in the library from my CDs. I only have these downloaded songs on one computer, the same as I've always had. I can see the files in the folder My Music/[artist]/[album]. I have QuickTime 6.5.2 and iTunes 4. I don't know of anything that's changed on my computer since the songs were working.
1) Is the problem that it's an old version of iTunes?
2) If I switch to a newer version, will I lose all my downloaded songs?
3) If the version of iTunes isn't the problem, any ideas about what could be wrong?
Please help! I've only had iTunes for a few months and have barely been able to use it. (I can't understand why it would become so outdated so quickly.) Thanks in advance!

Back up your purchased music before you upgrade, I've read at least 5 cases where purchased music has just gone.....missing.
That is not supposed to happen, didn't happen to me or thousnds of other iTunes users, but you don't want to be the 6th person, do you?
There are two things to try before you upgrade:

ITunes will no longer play nor add to the library any mp3 files which I have created by conversion from a wav file.

I am running iTunes 10 on XP Pro and it will no longer play those mp3 files which I have created by conversion from wav files. I tried to delete some from the library and then re-add them but iTunes will not add them back to the library.
Can anyone help solve this, please?
