Some background: I run a subscription-based poker strategy video website. Our videos range in length from 30 mins up to 80 mins, and in size from 20MB up to 500MB. The site is on a shared server with hostmonster.com

One of my users is having problems downloading some of the larger video file. He reports problems with anything over 100MB. Basically, he's only getting part of the file, which means that the video stops before the end. He has tried multiple computers from multiple locations. He reports that he is able to successfully download 500MB files from other sites.

He is using Internet Explorer (version unknown) as his browser. I have suggested that he try Firefox or Chrome to see if their download managers work any better for him, but as of yet I have not heard anything back.

He has also reported that his downloads do not report any filesize. I see the same thing (no file size reported), but I have not experienced any problems with the downloads themselves.

We pass the downloads through a php script which verifies login information and records the download to our database before returning the file. I suspect this is why there is no filesize reported.

What else should I ask the user? What other things could he or I try?
