Video too large (over 8MB)

I’m trying to upload an HD video 950 x 450
(i’m using a paid theme from graph paper press that allows HD Video)

I know this has been addressed before, but I have yet to find a clear answer to this problem. I have been told to modify the php.ini file and reupload it to my server. Do I put this in the root directory of my host server, or within the blog folder, there was only a php.ini file in the root (and not in the folder I have my blog in). Although I have now put it in both the root and the blog folder and it’s still not working.

This is the additional line of code I added to the php.ini file and it isn’t working:

upload_max_filesize = 50M
post_max_size = 80M

I have tried smaller values (20M, 50M) also but they didn’t work either .

I called my host and they say they don’t trouble shoot individual php.ini scripting issues, but they thought that should have worked. They don’t ignore the php.ini file.

can anyone help? I’ve been trying to uplaod this video all week. an HD video UNDER 8MB? It’s not going to look very High Quality, thus negating the point of shooting/posting videos in Hi-Def.

HELP!!!!
