No mime type found

[nomadsoul]

Hi and thanks for viewing my problem:
I made a php / mysql website that uploads and views videos. I'm quite sure the videos get uploaded successfully because they appear in the mysql db table as links to the videos. On the view.php page the error is 'No video with supported format and MIME type found' when I upload an mp4, and with m4v videos the error is: 'no file found' (generated from my own code). But I have added these mime types to the XAMPP config file. I don't think its the FF browser's problem because these videos play well from other websites.When using chrome the video frame appears in view.php but with a blank screen and the play button does nothing. I think the problem is either from the XAMPP side or php. The phpinfo page shows no information about video mime types.
Has anyone had this problem?

Thanks
