The software iPhone2iTunes enables you to browse and view your video files stored in the iTunes library on your iPhone. However, it only functions locally, unless your webserver is exposed with a substantial bandwidth.
One thing to note is that iphone2itunes only works locally. This means that, unless you expose your webserver and have access to huge amounts of bandwidth, you won't be able to access your media remotely. However, if you're using it in the intended manner- to watch videos on your iPhone- it works flawlessly. Overall, if you're looking for a straightforward way to access and watch your iTunes video library on the go, iphone2itunes is definitely worth trying out.
