Answer 1

My guess is your flv is probably just too big..
upload_max_filesize alone is not enough to set, you also need to set post_max_size otherwise your POST request will be empty and your upload will fail (it'll essentially look like a non-post request).

Answer 2

This line doesn't make sense
if(isset($_POST['action']) == "upload")
you are calling isset() which is going to return true or false depending upon if that variable is given a value and then you compare that true or false with the string "upload" which obviously would never be equal. You either need to check if the variable is set or check if the value is equal to "upload".
if(isset($_POST['action']) && $_POST['action'] == "upload")
Should also check for file upload errors. Something like:
if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_FILES["file"]["error"] . "<br />";
}
else {
echo "No file upload errors";
}
