    In the FAQ of RatDVD it's written that the maximum quality I can choose is 1200kbps.

    If so- do I miss something? because in a real DVD the bitrata can reach quite easily 5Mbps.

    I want a clear answer to the same question-
    Can someone make DVD-RatDVD translation from an original DVD, give me it so I do RatDVD-DVd translation and get the oroginal DVD IN THE SAME QUALITY EXACTLY, WITHOUT ANY LOSS?

    It's important, because there is a DVD in which I don't want to lose any bit, if you know what I mean.


    I remember the days when someone used to convert an original DVD into ISO, and then burn in on another DVD- I saw a loss of quality, probably because there was something encrypted as a detterent.

    Well, I've read that through RatDVD we don't lose any features, but DO LOSE quality.


    So I guess it's not for me. I want it to be in the same quality exactly.

    Well in all honesty how do you expect ratDVD to keep all the details in a DVD without the size of a DVD? ratDVD uses different methods mainly scaling to save information. Think about it if you take a photo and shrink it then blow it up again you get some bad details popping up. Just remember that sooner or later ratDVD will eliminate bits being lost. Also I suggest sitting away from the TV as you will not notice bits missing as much.

    I didn't expect it. Actually, I was wondering it, but didn't find a source saying there is a reduction in quality(untill I did find one).


    Anyway, is there a way to do what I want to do? Can I do something like that with creating ISO and then burning it?


    And,

    Whato do you mean? DVD is compressed by itself, so there is no chance rducing the size to 1.X GB and not having lost bits.

    I only say it might be possible as XEB does pretty good right now but if he updates XEB and gets the program working better then it should reduce bits being lossed.

    One thing you can try and do is to do a noise reduction via AVS scripting and (insert favorite encoding program here). Removing noise helps encoding as encoding only tracks color changes and video noise causes color changes so eliminating noise leaves more bandwith for important details. Be careful as AVS can remove too much noise and make it blocky.
