I fixed this, just passing along my experience...
ImgBurn has been successfully burning Blu-Ray discs for me for months. This week it stopped working. It would display the "Reserving Track" message and pause indefinitely. I left it running for hours, even overnight, and it did not get beyond this point. It was necessary to do a hard reboot (i.e., via power button) to get out of ImgBurn and try again. I assume that the drive or OS was never responding to the last step, or not sending the expected response.
Stuff I tried:
- Different disc manufacturer: Happened with both Memorex and Ri-Data.
- Different drives: Swapped my Lite Scribe with an LG.
None of the above worked.
I could still burn non-Blu-Ray discs (e.g., dual layer DVDs) successfully.
I checked the Windows update history and found that the most recent activity was an update installed 9 days ago (2014-10-02):
Update for Windows 7 for x64-based Systems (KB3001554)
Nothing else was installed at that time.
The MS info (http://support.microsoft.com/kb/3001554) is:
September 2014 update for DVD playback in Windows 7 SP1
"This update helps Microsoft improve customer experiences in DVD playback in Windows Media Player and Windows Media Center in Windows 7 Service Pack 1 (SP1). Check out the Prerequisites before you install this update, and see the "References" section about DVD playback."
I did the following:
- Go to Control Panel -> Windows Update -> View Update History -> Installed Updates (link)
- Removed the KB3001554 update
- Rebooted
I can now burn Blu-Ray discs again.
Sorry, I don't have any logs. Also, I should mention that one disc left overnight (before KB3001554 was removed) actually did complete successfully. But it paused for 6 hours on the "Reserving Track" step.
