The current recording system only records up to 5 or 7 minutes last I checked, but Phil Spencer has confirmed that external capture devices will be compatible with the Xbox One. For anyone that records Youtube videos on the Xbox, that is great news. I'm guessing that people who have capture cards will be using ir more often than the built in recording system since it records a whole lot longer.

Don't throw away your Hauppauges, your El Gatos or your Roxios just yet, YouTubers - Phil Spencer has confirmed that the Xbox One will still support external video capture, despite having its own built-in DVR capabilities.
