.wmv file downloading

Dear Sir,
i am facing a problem in downloading .wmv file.
while i downloded the .wmv file and then try to open it gives an error that file type is not supported. can any one tell me where is the problem in my php code?

re: .wmv file downloading

I don't see anything obviously wrong your code. Sounds like it's maybe your OS not reading the file correctly.

re: .wmv file downloading

Thanx for your quick response.

Can you tell me what will be problem at OS ?
i checked from different client's pc and all of them are using windows xp. and i am using apache 2.2.8 web server.
in all cases the same problem exist.

re: .wmv file downloading

Ok, that more than likely rules out your OS.

Trying setting the mime type (content-type) as 'application/octet-stream'.

re: .wmv file downloading

Now i am using the code like as below.But it remains same problem. the error is like that:
The file you are attempting to play has an extension that does not match the file format.

re: .wmv file downloading

Sounds like the file is maybe corrupt.

Minus the second content-type header.

re: .wmv file downloading

can you tell me what is reason file to be corrupted?
i tried the following code but it reamins same problem as before.

re: .wmv file downloading

Content-disposition may have to be 'attachment' not inline..

Does this happen with any file you try and download?

re: .wmv file downloading

i tried with the code as below. but it remains same problem. this problem is for vedio and audio files. but it does not happend in .doc or jpg files.

[code]
$videoName = "new_Ayman";
$videoDir = "download/tv-interview/";

$fullPath = $videoDir . $videoName;

header("Content-Type: application/octet-stream");
header("Content-disposition: attachment; filename={$videoName}");
header("Content-length: ". filesize($fullPath));
readfile($fullPath);
exit();
