Bizarre sync problems

I posted these two threads at the macrumors forums and they got over a thousand views each but no replies. Since then I've figured it must be a problem with iTunes but I don't know what more I can do.
... I don't even see a paste button here so I'll just link to those threads: http://forums.macrumors.com/showthread.php?t=1329404
After posting those I did a system restore to no avail. A full system scan with Avast! Antivirus turned up 0 infected files. Computer and iPod both seem to be running fine except for this one problem that came out of nowhere.
Please, if anyone has any ideas on what this might be, what I can do about it, where else I can ask, anything at all ...?

anyone?

IPad, iCal and iTunes sync problem

Early last year, I posted (https://discussions.apple.com/message/18503738#18503738) that syncing between my iPad 3 and my Snow Leopard iMac behaved oddly. AppleCare Support dweebs had failed to resolve the issue and no one on here managed to come up with any suggested fix.
However, for no apparent reason, the problem stopped and I stopped monitoring this august and highly esteemed forum and all went well ...
... until recently.
I sync via a USB cable and I do not use iCloud (as I'm on Snow Leopard) save for Find My iPad, all other iCloud options are switched off. All other app syncing appears to work correctly, it is only iCal and Calendars that don't.
Just why things have started to go wrong now, probably in the last three or four weeks, I do not know but now the following syncing errors occur ...
1) On the iPad: new appointments or changes to appointments made on the iPad are not synced to the iMac;
2) On the iMac, changes to appointments already on the iMac are shown on the iPad as both the new and old timings/details, not as replacements;
3) On the iMac, new appointments are made in the default (or last) calendar used. These are then edited as required, with the details put in and, if necessary, calendars changed. On the iPad, however, these will show as both "New event" in the default calendar and as the edited correct appointment, not just as the finalised entry;
4) Appointments deleted from the iMac are not deleted from the iPad.
In other words, changes on the iPad are not synced across to the iMac and changes on the iMac are synced twice, once as the unedited appointment and once as the edited appointment - if an appointment is deleted it remains on the iPad.
When the original problem arose (similar but not identical) the Apple dweebs suggested deleting my iCloud account (not synced, used only for Find My iPad) but doing that this time does not remove the bug.
I'm running a 27" quad-core i7 iMac under MacOSX.6.8 (Build 10K549), iCal v4.0.4 (1395.7) and I sync via USB and iTunes v11.0.2 (26). The iPad is a 64GB 4G/wifi iPad 3, currently running under under iOS6.1.3. To the best of my knowledge, all available updates have been applied to both devices.
I have deleted all calendars off the iPad by deselecting Calendars in iTunes' iPad tab, turned it off. Swicthed off the iMac, Safe Booted and run OnyX full suite, I have then Single User booted, run fsck -fy three times then run applejack AUTO restart, then rebooted the iMac, rebooted the iPad, sync'd without Calendars then resynced with the Calendars selected again.
I had hoped that this would remove any cache files, temporary files, stuck RAM or whatever else could conceivably be causing this bizarre behaviour - to no bl**dy avail! It is behaving exactly and frustratingly as before!
What on earth is going on? if I can't use my iPad as my main calendar and add new appointments when out and about and have them synced properly and reliably to my iMac then the whole thing is a waste of time andI shall have to revert to a paper diary again!
HELP!!!!! Please, before I go mad with frustration!

I'm not sure whether getting no replies to this (or the earlier) query is something of which to be proud - or terrified!
Am I the only person in the world with this bizarre insoluble problem? if so, why me? Am I a Chosen One or, more likely, someone to be punished for a lifetime of misdeeds!
But there is progress. I have no idea what happened at a technical level or why, but the matter has now resolved itself and things are syncing normally. Until the next time!
Perhaps there is a clue somewhere in the following ...
I run my iMac 24/7 and thus I rarely close iCal on the iMac and when i do it is usually by accident. The same applies to Calendars on the iPad, although I do reboot from time to time.
Anyway, I installed some software on the iMac which required a reboot and, as susual, iCal opened via Preferences > Accounts > Startup items - only this time I was presented with a perfectly blank calendar. A message appeared, from within iCal (oh, how I wish i had noticed what it actually said) saying something along the lines of "importing calendars". This took a little while and it wasn't instant - maybe it does this every time it reatrts but too fast for me to notice.
After this "import", if indeed that's what it was, the syncing was corrected!
Coincidence? Cause and effect? Magic? Too many magic mushrooms for breakfast?
If that is what resolved the issue, then how can I cause an import deliberately for when the syncing goes astray again and just what does an "import" do that a normal launch doesn't and which might have resolved the glitch?
I have had this "import" message before, but very very rarely, so it may well have resolved the syncing issue last time and I just didn't make the possible connection.
Does that help anyone come to my rexcue with an explanation and, possibly, a strategy for preventing or deliberatly correcting syncing issues in the future?

Audio Sync Problems With Share YouTube -- OSX not iOS

I've replicated this several times. It's maddening and bizarre. *Share YouTube*
Exporting a FCPX video using the "SHARE" menu and choosing YouTube causes the resulting upload to be out of sync when viewed in Safari or other browsers on iOS
Viewing the same video on the iPad with the built in YouTube app, the video plays in sync
Viewing the same video on AppleTV 2 (with the 5.1 update), the video plays in sync.
If I export using Export Media menu item under the SHARE menu, and then from QuickTime Player choose Export For Web (under the File menu) and manually upload, the video is in sync.
Note, that using
Feel free to try on this short simple and silly video http://www.youtube.com/watch?v=cGTQNMJdPRQ&list=UUiDxioBFJCPC-8OUFifsx8A&index=2 &feature=plcp
Anyone else experience this. Is this a bug or a feature? Rather not go through three steps to upload a simple YouTube video.

We've got the same problem and yep, it's infuriating that are so few posts about it.
It doesn't happen with every video, but the vast majority of files that we've tried to either export directly to YouTube from QTX or export locally and then manually upload to YouTube end up with shockingly bad audio sync (and also some colour issues, but that's another story).
As a small video production company we were chuffed to bits with the improved export speed in QTX and quick to make use of it. But when we realised there was a problem, we had to revert back to using QT7's painfully slow export.
We've run experiments on a brand new iMac and MacBook Pro running the most up-to-date version of OS X and still no joy. Always the same audio sync problems with the same video files.
In the meantime however, we've found that the settings advised on this YouTube help page have given us the best (albeit slow) results at both 25fps and 30fps when exporting from QT7:

'Source play' and 'audio-video sync' problems with PE8 on fast WIN7 64 bit computer

I am transferring Hi8 videos, about 2 hours long, to my WIN7 64 bit computer with PE8. [Dell Mobile Precision M4400 Computer Workstation (Intel Core 2 Duo T9900 500GB/4GB); NVIDIA Quadro FX 770M, 512MB] I seem to have several problems:
First, after importing the file (.avi), I get a message about ‘dropped frames.’
Secondly, when I try to play the video in the source monitor, the audio plays but the video doesn’t; it only shows the first frame [this is after waiting until the video is ?recognized? ] I can use the shift-arrow key and see that the video is there.
Thirdly, I can play the .avi file in other players, e.g., avidemux or PE pro CS5 on another computer. There, I see that the audio and video are not in sync; the audio can be up to 300 ms ahead of the video (as determined using avidemux).
Questions:
1. Why doesn’t the source monitor play the video? Is this a problem with PE8 (latest update as of 3 March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence?

"I think you're telling me you're using a backwards compatible Digital8 camcorder to capture your video as DV-AVIs. Is that right?" YES
"Are you using Premiere Elements to do this capturing?" YES, AS ABOVE PE8
"Go to the File menu and select Properties. It should show a standard DV codec being used for your video and audio."
WMP v12 is dumb. Under properties, media, it says 'video.' However, avidemux gave me the information state above: video -- Codec 4CC: dvsd, frame rate: 29.971 fps; audio -- codec: PCM, channels: Stereo, frequency: 48 kHz.
So, back to the Questions:
1. Why doesn’t the source monitor play the video? Is this a problem with PE8 (latest update as of 3 March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence?

Owning 2 iphones with one Apple account has = Sync Problems.

Owning 2 iphones with one Apple account has = Sync Problems. iTunes is thinking my old iphone 4 is the same phone as my iphone 5C. When I plugged in my iphone 5C it auto synced my 5C to iTunes and it wiped my 5C and restored it to the same content as is on my iPhone 4. This is a big problem since my 5 year old has been using the iPhone 4. It's all Mickey Mouse and Backyardigans. (Total photo/app/contacts loss)
I was able to update the 5C and restore from a 3 month old backup that is actually the content from the 5C but now when I plug in my 5C it wants to "setup as new phone" or "restore from backup" What's going on? I'm afraid to choose either option.
How can I get iTunes to see these devices as 2 and not one?
Can I use my Apple ID on both phones still or is this the problem?

They were both displaying the same name in iTunes. I changed the name of the iPhone 4 before the 5C was plugged in but it still went ahead with syncing it to the 4's data.

Outlook 2003 + iPhone calendar sync problem solved

Here is how I solved my sync problem. Seems a lot of people have the same problem here with Outlook sync suddenly not working after it worked fine for a long time.
I've had Outlook 2003 calendar sync with my iPhone for a few month without any problem, but a few days ago the sync suddenly stopped without any error message. iTunes Diagnostic found no problem and I followed all the steps that Apple outlines to fix the problem but nothing worked (TS2776).
As Apple asked to, I created a new user account on my Windows machine and setup a few test calendar entries to sync with my iPhone. That all worked fine.
So I did what Apple doesn't tell you, and I copied my original Outlook Data file (.PST) over to my new user account and tried to sync that one. Now this didn't work. So I knew the problem lies somewhere in my PST file.
I have then tried to create a new one from scratch in my original Windows account, and copy all the data over. Again, it didn't work. So I emptied the file again, and copied all my calendar entries over to the new PST file in batches (first 10, then another 10, etc).
What I found at the end is that one single calendar entry I created a few days ago caused my sync to stop working. Once I removed this entry, everything worked fine again. Don't ask me what was wrong with it (I made a backup just in case Apple wants to see it), but now everything works again.
If you want to save some time to find which one it is, you may start deleting entries that you created just recently before it stopped working.
Hope that helps.

Hi im having the same problem. I use outlook 2003 on windows xp and until recently my sync (using usb) was working fine. Now it would seem that calendar items are no longer syncing. can you give any further details of the calendar entry which was causing your problem? im wondering if it was added on a certain date perhaps.
I am running the inbox repair tool to see if my pst file has any problems but would appreciate any other help in the mean time.
Cheers

How can I sync my IPOD Nano 4 to iTunes on my PC? I've already tried the sync button on iTunes and it says it is synced. I've also tried the 5 steps recommended by Apple to fix sync problems with no luck.

How is your iPod configured to sync content from your iTunes library? Any error messages during the sync process?
You may want to reset warnings on the device by right->clicking on it under Devices and choosing Reset Warnings. Then resync the iPod to see if any alerts appear.
Is this the same computer you normally sync the Nano with?

How to stop the spinning ball/pizza that is stalling repairs to project on imovie 09? on macosx10.5.8 using iomega and superspeed ext h.d. as storage for the events and projects archive of a wedding video that has had audio sync problems on all share formats (iDVD, mp4, and last of all iTunes). The project label now carries signal with yellow triangled exclamation “i tunes out of date”.
To solve the sync problem I’m following advice and detaching sound from all of the 100 or so short clips. This operation has been stalled by the spinning ball. Shut down restart has not helped.
The Project is mounted from Iomega and superspeed ext hd connected to imovie09 on macosx 10.5.8.
What to do to resume repairs to the audio sync problem and so successfully share for youtube upload?

ICal Print List Hang / Font Issue / Sync Problems...

Okay, here's a couple issues all wrapped up into one thread/post - reason is cause I suspect they may all be tied together somehow, but am not sure.
Sync Problems...
Regarding the Syncing problems, you can find an ongoing thread about @ http://forums.markspace.com/viewtopic.php?t=1632
In short, some of us are having issues with events syncing to our Palm to the wrong timezone, causing them to be an hour off (usually within the new & old DST date change). Yes, all the usual fixes have been tried - pls read the thread noting "adairnet" and ymatto" postings.
Also, in addition to this time issue, I have iCal events that I've deleted in iCal still show up on the Palm after one-way syncing!
Print List Hang...
Every week I print a "list" of events from a certain calendar. The past couple weeks I noticed some lines in the notes field printing on top of each other. Twas odd indeed, but I hadn't had the time to look into the reason. Then this week I was going thru my usual printing proceedure and now iCal locks up, hangs up, crashes, forcing me to force-quit the program. It's usually after I extend the dates beyond 2 or 3 days, but I've not been able to find a consistency. I've redone events thinking they were corrupt with no success.
Font Problems...
After the Print List issue above, I opened my Console program to see if it was reporting anything. At first it indicated that it could not find Helvetica Neue and would substitute it for Helvetica. This put me in touch with some font corruption - so I got rid of those bad fonts and activated Helvetica Neue which got rid of that message. But made me wonder if there are more font problems causing the print hanging & syncing problems. I have FontAgent Pro and do have some font issues that I'm trying to work out.
But the Console is displaying another string of messages every time the Print List proceedure hangs up which I cannot figure out...
2007-04-24 16:24:54.151 iCal[28975] NSATSGlyphStorage inconsistency. Cannot find run storage for character range {138 67} for CTRun 0xDBE87D0. Ignoring the run...
2007-04-24 16:24:55.175 iCal[28975] -[NSMutableStringProxyForMutableAttributedString replaceOccurrencesOfString:withString:options:range:] called with out-of-bounds range. For apps linked on Tiger this will raise an exception. For earlier apps it will produce this one-time warning and continue with existing behavior (which is undefined).

So, all of this is causing me to wonder if the iCal or SyncServices database is corrupt. Is there a way to dig into the iCal db and check for corruption &/or fix it?
Or does anybody have any further suggestions on any of these issues?
thanx.jason.

RedKamel,
The SyncServices folder should be avoided like "a swarm of bees". This article discusses some of the issues that can arise when the SyncServices folder is deleted or modified:
http://docs.info.apple.com/article.html?artnum=301920
Data loss and Data corruption can result from deleting or modifying the SyncServices folder, and that data loss or corruption can be propogated to devices, .Mac, and other applications that sync with SyncServices.
If you have isolated an issue with the other steps in your post, I would recomend speaking with AppleCare before removing that folder.
Hope this helps,
Nathan C.

Ipod syncing problems...?

Im having several ipod syncing problems. I have an Ipod touch, 4th gen with the standard USB cable that comes with to charge it and sync it with. Today, i plugged it into my computer like normal to sync some new songs onto it from itunes. But, it started acting up. First, it kept syncing on and off, and the sync sound wouldnt stop- it wouldnt stay synced. then, later, when it finally did, not long after it said "this device does not support charging," and itunes didnt recognize my ipod anymore, so i couldnt sync my songs. is there any way i can fix this? thanks in advance.

- See:
iPod touch: Hardware troubleshooting
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store.

IPhone Sync Problems with VISTA After iTunes Upgrade to 7.4

Upon upgrading to iTunes 7.4 I was unable to sync my Outlook calendar or contacts to the iPhone. Called Apple Support that they seemed to know nothing about this problem general problem despite all of the discussions on this and many other tech. boards.
After being told remove and reinstall iTunes and Outlook, set-up a new user account, etc... (none of which worked) I finally concluded that perhaps the .pst file being used by outlook was simply incompatible with iTunes for some reason (e.g. unsupported recurring calendar items).
SOLUTION: Create a new outlook .pst data file. Once created, open up that new file along with the defective .pst file. Then, simply change the view of calendars and contacts in your old calendar such that you can see all of the items in a list. Highlight the items you want to keep and simply click-and-drag them to the nes .pst file. This solves all of the sync. problems I had post-7.4 upgrade. It takes less than 3 minutes to complete this painless fix.
This was so annoying for me that I'd be happy to help someone complete this simple task if they need help. < Edited by Host, for your protection, no personal information please. >

Then it would appear to be an issue with your router. What router? Model? Is the firmware up to date?

Thanks for any help!

- Have you reset your iPod:
Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Next would be to backup your iPod and then restore you iPod from backup via iTunes.
