Quicktime "Could not open movie" "An I/O Error occured"

I get this message (that the "Movie could not be opened" that "an I/O error occurred") when I attempt to open wmv, mpg or others with Quicktime. And yet they DO OPEN with VLC or other programs!!!
I got this when I started to copy files from my existing external drive to a new USB drive. They dont open on the new drive, and the files that opened yesterday on the old drive now dont open either (but ok with VLC).
Wierd.

You need to install:
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/
You should read this support page http://perian.org/#support in case you need to delete older codecs.

Error 8062 when I try to copy or move files on my macbook: "This operation could not be completed because an unexpected error occurred (error code -8062)". Can even not install new software now!!

Since a few days when I try to copy or move files on my macbook, I often get an error message saying "This operation could not be completed because an unexpected error occured (error code -8062)". And then it just quits the copy or move.
I searched a lot on the internet, but only found solutions for cases you cannot empty the trash due to this issue.
I tried those solutions for my trash and that helped after some trying.
However, I still have the problem with copying and moving files.
I even cannot install new software now, as it has to copy itself to the programs-directory, and gives the same error-message.
Who can help me??
Cannot seem to find any info on it on the support-forums or elsewhere.
My user-account is administrator, I use a 13" Macbook Aluminium (Late 2008). Mac OS X 10.6.8 CPU 2Ghz Intel Core Duo, RAM: 4GB 1067 MHz DDR3.
Any help would be greatly appreciated...

Tips I received so far (thanks to A-Mac via Twitter http://www.a-mac.nl and Remco Kalf http://www.remcokalf.nl/)
- make sure you have at least 10% of your harddisk in free space (I had only 5%).
- do a PRAM-reset (http://support.apple.com/kb/ht1379)
- perform a hardware test (http://support.apple.com/kb/HT1509)
- make a complete backup (with for example Carbone Clone Copier, see http://www.bombich.com/)
- after complete backup: use diskwarrior (boot from Diskwarrior DVD, first perform diagnostics, then perform "Rebuild" which rebuilds your file directory).
So far I only cleared up some space on my HD, and already the problem occurs less.
Still, I will go through the other tips too.
(will post progress)

My iTunes opens in safe mode but when I try to sync my ipad? It says apple mobile device service could not be started because an unknown error occurred 1084

It says apple mobile device service could not be started because an unknown error occurred 1084

I figured it out on my own, and it was an odd fix. I added a password to my account in users, and then made Apple Mobile Device service log in through my account, and now it works.

The iPod "iPod" could not be restored. An unknown error occurred (6)

I know this type of error has been posted before but I've tried everything I've read in other posts and have not gotten anywhere.
When I try to restore my Ipod Touch, after it is into the restore for a while, I get the message:
+*The iPod "iPod" could not be restored. An unknown error occurred (*6).+
iPod Touch 1G
Firmware 3.12
What I've tried:
- Rebooting host.
- Resetting iPod Touch - Holding down home and power for 10 seconds
- Using different computers with fresh versions of Itunes. Computers were running Vists, XP, and Windows 7.
- Putting iPod touch into DFU mode (Hold down Home and power for 10 seconds then let go of power until iPod goes into DFU mode.
I always end up with The iPod "iPod" could not be restored. An unknown error occurred (6).
I did get extended Apple care service but of course it ran out last month!
I did get a log from one of the failures if that would be of help.
Any suggestions?
Dave

Well my ipod is just out of warranty so I'm not sure if they will even look at it but I'll try tomorrow to bring it to the Apple store.
If anyone is interested here is part of the log file of the bad restore:

Help! Message "pdf could not be saved because an unknown error occurred. Try saving to a different l

I had the contents of my (dying) ibook transferred onto my emac. The tech created a new user/desktop on the emac. Now, when I try to open PDF files from a website, I get a drop down window saying this:
"Downloading - users/myname/desktop/xxxxx.pdf could not be saved because an unknown error occurred. Try saving to a different location."
Points to note: 1) The "xxxxx.pdf" part of the above message changes each time I try to open a pdf document, even the same one, and it does not show the real name of the document (e.g. CollegeApplication.pdf). The xxxxx.pdf is usually written as gibberish, like "86hgkjh.pdf" or "sdfj99f.pdf."
2) this never happened on my laptop;
3) the settings are set in Firefox to download pdf's to my desktop;
4) I have the latest version of Adobe Reader, which I already tried opening before downloading;
5) the settings are also set to open pdfs using adobe.

I had the same problem when I installed Firefox 3, but I think the problem is due to my recent hard drive upgrade. Try changing the download location from "Desktop" in Microsoft Internet Explorer and all other browsers (Safari, Firefox, etc.) to whatever default location you prefer. I never use Internet Explorer, but I think somehow my settings were corrupted when I upgraded my hard drive. I found this solution on another site also.

The document could not be saved. an unexpected network error occurred

I have several users on a terminal server that access a PDF from a file server. This PDF has many fillable fields like Name: with an empty text box next to it.
Sometimes when the users open this PDF everything is missing except the fillable text fields. If they try to save the file they get the error in the subject of this ticket:
the document could not be saved. an unexpected network error occurred
Obviously, this sounds like a networking error, but 2 things.
1) The terminal server and the file server on both virtual servers on the same host, using the same SAN. Very unlikely to have a networking error.
2) This doesn't happen to every, it seems to be only affecting 3 of about 25 right now, and it is not all the time.
Any thoughts? I have checked to see if there were any hidden lock files, but that wasn't it. Google-fu turned up nothing.
Thanks for your help

Hey jdorimoto,
Could be please confirm if you are using Adobe Reader or Acrobat (what version) to open a PDF form.
What version of OS are you using?
Try saving the form to any other location with administrative privileges and then check.
Hope to get your response.

I am getting an error message on my itunes when trying to back up my iphone 4s, itunes could not back up iphone because an error occurred.

Please help me!!!! I have tried all of the steps that I have found listed for this issue. I am not sure if I should try to contact my phone provider or not. I am getting an error message without an error code. That says: Itunes could not back up Iphone because an error occurred. Please if anyone one knows any steps I should take please let me know. My iphone and Mac and iTunes are all up to date.
Itunes: Version: 11.0.2
MacBook Pro: OSX: 10.8.3
iphone4s: iOS 6.1.3
Thank you

Excellent!
Please note the following:
Note: iCloud Backup does not back up music, movies, and TV shows that you did not purchase from the iTunes Store, or any podcasts, audio books, or photos that you originally synced from your computer. iCloud Backup will restore your purchased music, movie, and app content from the iTunes and App Stores during the background restore process. Previous purchases may be unavailable if they are no longer in the iTunes Store, App Store, or iBookstore.
The above comes from this article:
Choosing an iOS backup method (Should I use iTunes or iCloud to back up my iOS device?)
Best of luck with this.

The iTunes Library could not be saved. An unknown error occurred -50

I moved my itunes to an external drive that I am accessing wirelessly (it is pugged into by time capsule). When I open itunes I can see and access all of my songs and videos fine but I keep getting the error message "The itunes library could not be saved. An unknown error occurred -50". This must have something to do with moving itunes to the external drive but I can't figure out how to stop this message. I am running itunes 10.4.1 on Mac OS 10.7.1.
Can someone please help?
Thanks,
Lisa

I have a pop up window that says "Sorry the operation could not be completed because an unexpected error occured (Error code -61). What does that mean?

I am using a portable USB storage drive connected to my laptop. I am trying to delete a file from the USB drive but it is not working. A pop up window appears that says "Sorry the operation could not be completed because an unexpected error occured (Error code -61)". What does that mean and how do I fix it? Thank you.

All I can tell you is that is a write permissions error. How is this drive formatted? Check the file's permissions. You can try:
Open the Terminal application in the Utilities folder. At the prompt enter:
sudo rm -rf
Leave a space after "-rf" and drag the file into the Terminal window. Press RETURN. You will be prompted to enter your admin password which will not be echoed.

The ipod "ipod" could not be restored. An unknown error occurred (1602)

After trying to update ipod, during the phase where I had to back-up the ipod, an error message popped up (I can't remember what it said). Now, the ipod is just stuck on the "plugin to itunes" icon. Itunes and my computer can't recognize my ipod anymore. I have tried putting it into DFU mode and my computer detects my ipod and begins installing the drivers. On my first attempt, the drivers installation failed, so I reinstalled itunes and quicktime. Then after putting it into DFU mode again, it begins installing the drivers, but this time it was successful. Now I had the option to 'restore' my ipod so I did what I could. However, when I was installing it, 2 more drivers had to be installed and they were successful, however, I get this error message:
The ipod "ipod" could not be restored. An unknown error occurred (1602)
Any help would be greatly appreciate. Thanks very much for your time.

Error 1600, 1601, 1602: Try the following steps to resolve this error:
Ensure proper USB isolation troubleshooting has been performed, and test with a known-good cable.
Follow the steps listed for Error 1604.
This error may be resolved by disabling, deactivating, or uninstalling third-party security, antivirus, and firewall software. See steps in this article for details on troubleshooting security software.
Error 1604: This error is often related to USB timing. Try changing USB ports, uninstalling and reinstalling USB ports, and other available USB troubleshooting steps (troubleshooting USB connections, device not recognized properly, computer won't recognize a FireWire or USB device). If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode,put it into Recovery Mode.
Restore and wait for error 1604.
When prompted, click OK.
Close and reopen iTunes while iPhone remains connected.
iPhone should now be recognized in Recovery Mode again.
Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.

CS4, Save PNG: "Could not complete your request. An error occurred."

Using Fireworks CS4 (v10.0.3.011), when I have been working on an image for a long time, with a long undo history list, if I attempt to save the image as a PNG, I receive an error "Could not complete your request. An error occurred."
I am on Windows XP SP3 (32-bit). This error typically occurs when page file usage is around 2.4GB.
If there is a limit to how much RAM/pagefile Fireworks can use, can a warning not be implemented?
eg. you are about to pass the point of no return, at which stage your document will become unsaveable.
Is there no way undo history can be purged while an image is open?
This would dramatically reduce RAM/pagefile usage and potentially make the image saveable again.

My OS is 10.4.11. on 2 GHz Intel iMac.
I reread my orignial post and noticed a typo. I can save png's with PS "save for the web," but can't open those just-saved png files.
I did lots of things before I noticed that the png wasn't working. Don't know which may have caused a problem. Likely things? Well, I added a plugin for Ico. format. I deleted it because I thought it might have caused the conflict.
Assuming that was the problem, what can I do to restore the png file format?
I don't have disk warrior. I did run the maintenance utility yesterday. It runs crons, clears caches, deletes cookies, that kind of stuff.
I've never had a problem with it disabling plugins or causing any problems. Haven't run disk utility for a few weeks. Would that help?
I didn't download the replace png plugin from Adobe, but the original wasn't working anyway. I looked for a backup on the exernal drive, didn't find one, and downloaded another.
Next, I did a Photoshop reinstall thinking that might fix the problem, but it didn't. Which plugin folder should the png plugin be place in. I've never been sure why there are two format folders; the folder in plugins, and the folder in Photoshop only.

The iphone could not be restorted. An unknown Error occurred (21).

when i restore my iphone using itune this error pop up".The iphone could not be restorted. An unknown Error occurred (21)". what should i do? my iphone cant open..

This is a solution to this problem, but you have to have all your iPhone data backuped before you set the iPhone into DFU Mode (Device Firmware Upgrade Mode)
Please Follow the following instruction Step by Step
     - Connect your iPhone to your Mac or PC via the 30-pin connector.
     - Hold Power and Home-Button for ten seconds.
     - After ten seconds, release the Power Button, but keep the Home button pressed until iTunes sees the        device.
     - Once your device into DFU mode, there will only be a black screen on your iPhone.
If you successfully performed these steps, iTunes will give you a message that a device was found in Recovery Mode and restore it to be.
Now you SHIFT and Restore in iTunes button to press together, so that iTunes can refer to the IOS firmware to which you are restoring. If you have followed these steps you shouldn't get the Error 21 anymore.
