If you’re owner of HTPC with Video Disk Recorder (VDR) and have enough interesting recorded media content you might use vdrtube to share it similar way as it’s done with YouTube. That VDR plug-in adopt video to display in Flash-player and build HTML structure to access it via web browser.
Plug-in allows to create themes. So, you can customize YourTube according to your desire. Also, there is a possibility to control access to your media content using Apache authorization functionality. Plug-in vdrtube is developed on Perl. It’ll be pretty easy to modify it if you don’t satisfy its work.
Actually, it’s a good possibility to share your video between relatives or friends. But personally I prefer to have plug-in which allows to watch YouTube video on TV using VDR or MythTV. But currently as I know only Windows MCE offers such feature.
