    so at what percent would you REALLY be able to tell a significant sacrifice in picture quality, on a single layer DVD?

    for example, FlyBoys is around 70% compressed on a SL dvd+r, i have a 32" LCD tv with component video cables going to my DVD player. would i be able to tell a huge difference from it requiring no compression?

    the reason why i ask is, DL discs are significantly more expensive than single layers (even when on sale). opinions?

    i normally do just main movies so they seem to not need much on compression. .when adding al the extra then compression gets heavy

    i have a 32" tv also but a full disc backup of flyboys on a dvd-5 looks fine to me on mine.

    flyboys is big, about 7.3 gigs on just movie + menus.

    i took out all the unecessary languages and got it to 70% compression exactly on a single layer dvd.

    I have an LCD TV also. Any disc I write with 70% compression looks
    fine to me. I usually do movie only because I get 100% sometimes.
    I have also run one of these on my son's upconverting DVD player.
    They work very well with that too. I'm using a Philips DVD player.
    You don't need the chapters on it because for the last 5 movies
    played it will automatically start where you stopped watching.

    Hi ZCS626,

    While you probably aren't going to notice any difference there is a loss in quality. Maybe if you were watching that movie on a 60" Digital TV you might notice a differance, but again the average person won't be able to recognize the difference.

    Compression is a funny thing when it comes to video because it really isn't compressing at all it is actually removing pieces of video from certain frames. Do yourself a favor and read this it should help you understand a little better about video compression "Video Compression
    and if you really want to get smart try this one MPEG-2 Video Compression
