I am having a problem when I open AVI files that I create from the video camera. When I select them I get a message that reads ' Dr Watson Postmorten Debugger ' you have a problem’. When I click the box to close it, it locks up the computer and I have to do a soft boot.
Sometimes it brings up the Microsoft error reporting message that you have a problem and closing you down. I click on don't send message and I go back to the desk top.
I opened [Windows file folder for error message debugging]. There is a lot of files in the folder telling me what has been done.I also am getting the Window Explorer message, when I click on a AVI file and when I click don't send message it closes me back to the desk top.
Do you know what might be happening.
I know Phil does a lot of video editing and makes some great photo and video keepsakes for his family. Like most of us he has tried a few different programs and Windows being the complicated software that it is he has in the past had some trouble with file formats and such. So I was thinking that this might be another recurrence of your old problems.
But a little bit of research reveals some more info. Once again the sheer volume of help available from Google is mindboggling – you just have to know how to search.
I found this discussion thread at a forum called MovieCodec.com. The details here are exactly the problem Phil is having.
Windows has a default habit of offering you a preview of multimedia files when you are searching through Windows Explorer. You know how when you open My Videos or whatever and select a video and Windows wants to show you a little preview copy – that’s what I mean. Ok so what happens is Windows (well Windows Explorer actually) takes control of the file and then when you try to access it the file is ‘in use’ and Explorer locks up and requires a restart which a lot of the times will mean restarting your whole system. This lock up triggers the Windows error reporting messages and Dr Watson which is Windows debugging program.
What the linked info suggests doing is to de-register the Windows settings, specifically a DLL file, that do the preview function. By so doing it can avoid this lock up problem altogether
The easiest way is to run a command through the ‘Run’ setting or to save the settings as a Batch file. A batch file is just a plain text file but with the extension changed from txt to bat. Running a batch file is like double-clicking a program file – the simple code written in the file will run. For that reason some antivirus programs will rightly try to block batch files. More Info on Batch files is available here at Wikipedia
To help out I have made the batch text files for you and you can download them below. There are 2 files – one turns the setting off as described and the other turns it back on.So if changing it didn’t help or you wanted to go back to having the preview you just run the On file.
WinShellMediaOff – turns OFF the Windows Shell Media Handling
WinShellMediaOn– turns ON the Windows Shell Media Handling
Click and save the file somewhere like your Desktop. Once saved right click and choose Rename and change the extension (the bit after the dot) from name.txt to name.bat. Then double click the bat file to run it. If you want to see the contents of these files just open the Text file and read before you change the names to bat or read the website.
So give this a go Phil – I reckon it will work and shouldn’t do any harm if not. Other people on the site say that downloading the newest DivX codec solved their problem.So if this fix doesn’t work that would be my next suggestion. The latest version is always available at DivX.com
Let us know how you go :)
