Ok, I recently got a hp x5400 media extender and am wanting to watch ripped videos. I have the videos ripped into .vob files (mpeg) and .ifo files, problem is, the media center app does not recognize these files, just says I am browsing a blank folder. I installed powerdvd and started the files in media player to get the codecs and such but still no luck. Any help would be greatly appreciated.
