Steve Jobs also claimed that a large percentage of the video on the Internet is supported on iOS, since many popular video sharing websites such as YouTube have published video content in an HTML5 compatible format, enabling videos to playback in mobile web browsers even without Flash Player.
Hauppauge MediaMVP
The MediaMVP supports the MPEG (MPEG-1 and MPEG-2) video format (and "only" that format). However, depending on the MediaMVP host software running on the host computer, the host software may be able to seamlessly transcode other video file formats before sending them to the MediaMVP in the MPEG format. The maximum un-transcoded playable video size is SDTV (480i). HDTV mpeg streams (e.g. 720p) need to be transcoded in real-time on the computer to SD format. Note: transcoding video can tax some slower computers.
