With years of collection, we amassed a large amount of recorded & ripped videos in multiple formats. They are stored in an HP MediaSmart Server, which is an UPNP Media Server & DLNA compliant, and in some NAS drives. We play the videos on TV by streaming wirelessly using Media Players (WDTVLive, Roku, etc . . .) and randomly to Android tablets. Never could we stream anything to our iPad. We tried several players, paid and free, none would access the server. Some would access a computer with certain limitations. We are about to give up trying. Until we found this: OPlayer HD By olimsoft $4.99 https://itunes.apple.com/us/app/oplayer-hd-best-video-music/id373236724?mt=8 Compatibility: Requires iOS 4.3 or later. Compatible with iPad. OPlayer HD is used to boost your iPad's media abilities, you can also use it to streaming audio and video over the internet.

OPlayerHD Lite - the best free video and music media player for iPad By olimsoft https://itunes.apple.com/us/app/oplayerhd-lite-best-free-video/id385896088?mt=8 We tried the HD version. It accesses and streams flawlessly avi, mkv, mp4, m4v etc... in h.264 720p. Of course it plays downloaded videos beautifully. There are other features which we haven't try. Perhaps we could receive recommendation from other users for similar great apps and/or the uses.
