Not only does it let you watch HDTV, but you can also record it on your harddrive. Yes, the full 19.4Mbps stream of 8VSB is stored in raw format. Now, if somebody out there could just make some linux drivers for it ..."

    According to the article, the recorded video is in fact encrypted - only the specific card that did the recording will be able to play back that particular stream.

    As this is a 19.4Mbps raw format file. I persume that bits.

    So.

    19.4 x 1024 = 19865.6 Kbps
    19865.6 x 1024 = 20342374.4 Bits Per Second

    Now lets divide by 8
    20342374.4 / 8 = 2542796.8 Bytes Per Second
    2542796.8 / (1024 x 1024) = 2.425 Mega Bytes Per Second

    Now, I would like to record a move of 2 hours

    2.425 x 60 x 60 x 2 = 17460 MB
    or 17460 / 1024 = 17.05 Gb

    Thats alot of space , evan for a 80mb hard disk.

    Just a question someone might be able to answer, how well will this compress ?

    If its a good level of compression, will it allow a new way for the napster type people to break into a new medium.
