Phpbb2 attachment mod problem



Has anybody noticed certain attachments not working correctly. For example avi and mov files will be viewed in a browser as text. It appears the header is not being sent.
This problem occurs in IE 6, 7, and Netscape 8. Firefox downloads the file then plays, as does Netscape when emulating firefox.
Video files will work in inline mode, just not as a download. For some reason wmv works fine.
I tried to get an answer from phpbb forum, but did not get answer.
Oh, btw phpbb 3 beta works fine.
