Once the videos are converted you can then add them to your media server's library. With some DLNA servers that's as easy as placing them in a specific directory. With iTunes, you need to add them to the library. I highly recommend that if you use iTunes you head over to the iTunes Advanced Preferences and choose to "Keep ITunes Media folders organized" and to "Copy file to iTunes Media folder when adding to library." This will make managing your video library a lot easier.

In either case, place your video library on a very large drive. Video files are big. The average standard definition movie in my library is almost 2GBs in size and my 720p HD movies clock in at abut 7GBs. Even a TB drive starts to look small with these files!

Once loaded into your media server, you should be ready to watch your own private movie collection on your TV whenever you want. Enjoy!
