I'm running into a similar issue.  I am storing media files in the repository module, and it appears that the module is only allowing a download to last approximately 90 seconds before prematurely ending.  For example, I start a download of a 13mb file, it downloads for 90 seconds, and then acts as though it is finished.  When I look at the downloaded file's properties, it only has downloaded around 2.8 mb.  Is there a timeout set for the download aspx file?

I've also noticed that the download speed is slower than it is in the Documents module.  For example, when downloading the same file as above from the Documents module on my internal network, the download is almost immediate, approx 7mb/s transfer.  When I download the same file from the Repository module, it runs 90 seconds, at approx 50 kb/s transfer.  Is there also a download/bandwidth limit that is causing it to transfer at a slower rate?

This is the only real issue I've found with this module. I want to thank you for all the work you've put into it, it is an extremely flexible tool, and I appreciate your hard work.

Thanks again!

If you upload the same large file using the Admin->File Manager or Host->File Manager, do you see the same problem if they then try to download it via the built-in File Manager module?

The reason I ask is that the Repository module is using the exact same code as the core file manager  to download files to the browser. I would expect that you would see the same behavior.

Can you tell me what your 'different solution' was. I have a client who is using the Repository for uploading and downloading music file ( 100's of megs each ) without any problems.
