Dear Micah,

I have the following segmentation violation problem when using your function:

>> [video] = mmread('br100.avi')

Warning: In the directory
"C:\mmread",
mexDDGrab.mexw32 now shadows
mexDDGrab.dll.
 Please see the MATLAB 7.1 Release Notes.

Stack Trace:

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

If it is an official MathWorks function, please
follow these steps to report this problem to The MathWorks so we
have the best chance of correcting it:

The next time MATLAB is launched under typical usage, a dialog box will
open to help you send the error log to The MathWorks. Alternatively, you
can send an e-mail to segv@mathworks.com with the following file attached:

Any idea on what it is happening here?

Many thanks!
