Ask HN: How kind of digital asset management systems do you use?

For our current website, we are processing and generating a lot of large videos recordings, audio recordings, and photos which is spread across multiple employees and 2 far-flung locations. For our current workflow, I'm working on consolidating all those digital assets in some kind of system.

An off-the-shelf solution like a HP MediaSmart Sever that runs Microsoft Windows Home Server seems attractive since I rather spend be coding. It would consolidate media on one site, although I'm still fuzzy on how to sync up 2 different locations (probably do some hard-disk hotswap).

(A hosted solution like putting it in the cloud is not really in the picture due to the cost and upload time inflicted by the raw videos footages. They're multiple GBs per hour.)
