    Default pressing "i" on keypad during playback

    Can someone breakdown what it is showing me please?

    I get things like:

    D(video h:264 (High), yuv420p 1280x696)


    Why is that 420p?

    Most of my videos are 72p or higher. How can I tell what the true quality of playback is?

    Thanks

    420p is not a resolution when you're talking about the YUV colorspace.

    video h:264 (High)- The codec of the video stream

    yuv420p - The colour profile of the output (or "colour space")

    1280x696 - The resolution of the source stream - assuming your TV is 720p or higher, the full video resolution will be displayed on your TV. (this steam is less than 720 - it's 696)
    Boxee Box > HDMI > HDTV

    Great thanks. So this is the bit I'm interested in.

    My tv is only 720p. What would be the reason I only get 696? The file? The streaming? the tv?

    Thanks again

    You can confirm the resolution of the file itself by using "media info lite" and running it on the file. The output will tell you all the stats about how the file was encoded.

    As I understand it, a HD video will only have a resolution of 1280x720 if it has an aspect ration of 16:9 (or 1.77:1). A lot of DVDs have aspect ratios of 1.85:1 or 2.35:1, which is why you still get black borders at the top and bottom when you play them on your widescreen television. Your 1280x696 video probably has an aspect ration of 1.85:1 (dividing 1280 by 696, actually gives 1.84, but somebody who knows more about pixels and aspect rations than me can probably explain that).
    I have checked one of my HD videos which as a 2.35:1 aspect ration and the resolution is 1280x544.

    Here is a site with more information:
