So I’ve gone through all the trouble of preconverting all my media. When I bring up the web interface in ipad / ps3 / xbox, video launches right away and I can move forward and back through the video at will. No transcoding as expected.
However when I use my iPhone 4, it transcodes. No matter what settings I select in the transcoder settings, even NEVER on When to Transcode, it still transcodes. So I installed a little user agent faker app (gotta love jailbreaks) and had my phone report itself as an ipad in Safari. Boom. Video fires right up, can select anywhere in video. NO TRANSCODING! YAY! This also works using a pure uPnP player like AcePlayer.
This really needs to be addressed. Was driving me nuts. There’s no reason tversity should be transcoding preconverted files for an iphone.
