I posted this on lightroomforums.com as well but figured I would syndicate the content here, since the audiences are probably different.
This might be a little bit of a long post but I'm flat out of ideas. I usually am able to figure most things out but this one is beyond me.
I am having issues importing existing videos that are on my NAS.
Here is my setup:
Local PC with lightroom installed. Core i7 3770k, 16gb RAM, GTX570 video card, Asrock z77 Extreme4 motherboard, Win7 64 bit, 120GB SSD for the installed apps and OS
Nas is a Synology Diskstation DS212 with 2x 1.5TB drives in RAID-1 connected via ethernet (CAT6) through my Linksys WRT-610N router.
I have about 25000+ pictures on my NAS taking up about 180gb of space. This includes probably 1000 video clips ranging from full length home movies that have been converted but also a lot of shorter clips taken from a cell phone, my T2i DSLR, my GoPro, or prior to all that a Canon SD800. Most of the video formats are in AVI or MOV.
Anyway, all my pictures import fine, but when I try to import videos, I can sometimes get a few to import, but then it runs forever and I get an error popup saying "There was a problem importing the video". Note that this is ONLY for existing media. Direct imports from my cameras work completely fine. All the videos I tried also play fine in other players (quicktime, WMP).
Yes, I do have Quicktime installed and it is updated. I have tried both Sync and Import (ignore duplicates) as well as try even just a single video file and I get the same issues.
INterestingly, the same time when import crashes on the videos, I can no longer play any videos that were previously improted. I get a "Error playing this file" pop up message. Usually before that happens, I can scrub across the video clip in Grid view and see the video play. It won't work in Loupe view however.
I have tried many things, including a 4 hour conversation with Adobe support with remote PC control and multiple restarts. WE tried:
1. Disabling all startup services and tasks
2. Disabling AVG anti virus
3. Creating a new profile
4. Creating a new Lightroom catalog
5. Uninstalling and Reinstalling Lightroom
6. Importing and working on videos from the desktop instead of the NAS
7. Deleting the Video Cache in preferences
And all have the identical issue. It might work for a bit, then stops.
The only way I can get vidoes to work again is CTRL-ALT-DEL to Task Manager, killing the two processes dynamiclinkmediaserver and dynamiclinkmediamanager, and then restarting lightroom. I get a few minutes of operation and then it doesn't work again.
When we tried earlier with disabling everything and creating a new profile, I did have some success for a while, but after I got up to over 3000 pics it started failing again, so I'm not sure if it's a volume issue, however new catalogs with only a few videos freeze also so I doubt that is it.
There must be some conflict somewhere and short of reinstalling my entire operating system I am stuck. Anyone else experience this?
There are some topics on Adobe for this already but the response has been insufficient or lacking a solution, obviously.
Another forum topic, which had the suggestions on disabling dynamic link manager and media manager http://forums.adobe.com/message/4131378
Photos work fabulously, both RAW and JPG and DNG, no issues whatsoever.
I'm so frustrated by this :/ One more note, a full system reboot will usually again let it work for a little while (like, a few to 10 minutes)
