Why not? iPods, phones, PSPs, are all going to have similar capabilities in terms of their hardware decoders (and none in terms of software decoders). TVs are likely able to playback anything you record directly. That means its a single transcode to support most devices available. A near term plan for MythTV by one of the devs is to rework the storage of recordings, to allow multiple files to be stored against a single recording. This would significantly improve management of multiple transcodes.</blockquote>
<div><br> It would be wonderful if a single encoding could be used with all devices, but I don't think it is realistically possible. The bit-rates and resolutions for small mobile devices (iPhone, Droid) are going to be different from those used with tablets (iPad) or your high-def television. On-the-fly transcoding is a very difficult feat. I think that the best solution for now is to have a powerful MythTV back-end with a multi-core processor that can transcode recordings shortly after recording.<br>
