This is a scary bug that somehow has slipped through the beta testing process. If you want to read all the posts then click here, but here is a synopsis of the issues and suggested work rounds…

nhaudio outlined the basic problem…

Just updated ProTools to 8.0.3 on two systems and have found a major problem:
If I save and close a session that has a video file in it (.dv which is going out firewire to a Canopus ADVC110), when we try to reopen the session, ProTools ‘Unexpectedly Quits’ when trying to rebuild windows (the last few status updates you get when a session is opening).
Sessions with no video file open fine, no problem whatsoever.
We can’t work like this! We open various tv commercial sessions all day, and rebooting each time is brutal!!!

Digidesign pitched in very quickly and asked for crash log file details…

In Pro Tools 8.0.3, we added better and more robust logging to help track down problems like the one you are seeing. When Pro Tools crashes, some information about the crash is written out to a log file. The log files are kept in the “LogFiles” folder that is next to the Pro Tools application.

Here’s what you need to do…

1) Reproduce the crash you are seeing.
2) Look in the LogFiles folder and find the latest log file. The file name ends with .dlog
3) Email this “dlog” file

There is no need to do it now as the list of posts confirming the problem grew very quickly and Digidesign quickly confirmed they could reproduce the problem…

We can now reproduce this bug in our test lab. We’re still investigating what is going with this bug and are trying to narrow down the root cause of the issue.
It looks like there is some combination of changes that were made in Pro Tools 8.0.3 and updates to the Apple QuickTime software that introduced this issue.
I’m glad to see there are several workarounds for this problem, albeit not particularly nice ones.

Also two workarounds came through from users. The first came from nhaudio…

I’ve found a workaround for now. It seems if the Canopus is powered off when I launch a session, it opens fine. Then I can turn the Canopus back on and work as normal. So for now, I plan to turn it off before opening any session to keep workflow… well… flowing.

And the second from stustan…

I also have the exact problem but I have a different work around that is 100% effective. Instead of bothering with the Canopus Box which is out of easy reach, I rename the pix folder by adding an X to its name. PT 8.0.3 LE then opens perfectly with the relink window informing me it cannot find pix. I then relink to the renamed folder and all is well. The next time I need to boot the session I rename the folder again, usually back to the original name and go through the above steps. My pix folder’s name then flip flops between Pix Folder and XPix Folder

Then diamondscwin chipped in to say…

at the moment it seems to me that Quicktime playback and 8.0.3 is broken… people in this thread are reporting issues with Blackmagic cards, AVID Mojos, Canopus boxes and just desktop playback… only cure regardless of OS is rolling back to 8.0.1 so I dont think its apples fault.

Then uno1234 was one of several that suggested…

We are reverting all our 4 systems back to 8.01. As nasty as that 8.01 bug list is, we just can’t deal with firewire out crashing anymore. How exactly does an official software release get so bungled up like this? Was there no beta testing in a simple post production workflow? Is there ANY accountability at Digidesign anymore?

Also to note that the 8.0.3cas1 update hasn’t fixed this problem so it would seem that for video post facilities using video peripherals should say on Pro Tools v8.0.1 for now.
