Video Download Timeouts

Greetings everyone - loving Dreamhost!

I’m trying to use a php script to pass large files through a http header.

It’s a video file - and the one I’m using for testing is 160.7 MB.

Every time after approx 6 minutes – download completely stops.

Has anyone seen this problem before, better yet, have you been able to fix it?

Thanks to anyone for any help you can provide!
