yeah the more info would defintely help. Try Rev's suggestion for the system restore. If that is possible it should restore your registry back to a better version that doesn't generate this error.

Can anyone reproduce this error? I am going to give it a try..

If indeed this registry fix doesn't fix it for you, you may have to try this:

Another method for deleting problem files (not just avi files) is by closing explorer and using the command line to delete the file. Here I'll give you a method that doesn't require you to enter any paths.
Find cmd.exe (it's in your Windows\System32 folder) and COPY it to the folder that contains your problem file.
Double click the copied cmd.exe and leave the dos window open.
Then click Ctrl-Alt-Del and choose Task Manager>Processes tab. Select Explorer and click End Process.
Once ended, enter your delete command in the open dos box:
del mymovie.avi (where "mymovie" is the name of your avi file)
Press Enter.
Then press Ctrl Alt Del again to get to the Task Manager>Processes tab.
Click File>New Task.
Enter EXPLORER.EXE and click Ok to get Windows back to normal.

The file should now be gone.

Kind of a long way to delete an AVI file. Personally I like the reg fix.


Please do post the details of that error though.
