I pretty much only use the media library for adding images to posts. I completely gave up on using it for video.

I use flash comm rtmp servers for my video's, and the media manager has no idea how to deal with rtmp streams. Frankly it kind of sucks. It would be so nice to see a version of the media gallery where I could input the rtmp streamer settings, as for the most part none of that ever changes.

I have my own custom panel that allows me to easily create advertising campaigns, so adding in pre/post roll commercials is very easy. It even creates the thumbnails for me for the video player itself.

I even tried the videopress plugin, but after having a number of real dev's look at it, it was finally decided that there is no way to get that plugin to work with rtmp streams.

Then there is the problem of not having folders within the media gallery for sorting images. I can't even imagine using the media gallery for my photo sites, as most of them contain between 300k-2mill photo's... that would suck bigtime in wordpress with no sorting.

It's almost like the entire media library concept is nothing but an afterthought with wordpress. Bottom line for me.. it sucks
