  1. Just wondering why commercial video DVDs have a higher capacity that
    the blank discs I normally buy eg DVD-R etc. Am I correct in that the
    former is single sided? And if so can I get higher capacity single
    sided writeables?

  2. Yes, double layer. They've gotten quite a bit cheaper.

  3. To clarify, commercial DVD videos are double layer?

    If you want high quality and long record times, you need double layer.

    The last double layer discs I bought (Verbatim) are rated for 8.5G/240
    minutes, and a 2.4X record speed. You need DVD DL hardware for these.

    I can put only an hour of video on the single layer discs I buy.
