InstantCopy and DVD2One beaten within a few weeks?

i just made my mind up and 'discovered' the ultimate disadvantage of those tools: they relay on the motions vectors of the original file beeing correct.

i bet, that it only is a matter of weeks until the studios make maximum-bitrate-dvds with wrong/stupid motion vectors due to patched encoders, which move picture parts which wouldnt be needed to move and is invisible to the human eye. and because most movies are made on dvd9-medias with MUCH space left it wouldnt cost them just _NO_ cent extra.

when those movies are transcoded with the new 'revolutionary' tools they only produce noisy pictures, because the vectors eat up too much bitrate. dont tell me i paint in black, but this is too obvious to me...

at least it currently works - doesn't cost that much, and if the new titles come along, you've only wasted 15-30mins converting it :)

hmm.. first of all studios use hardware encoders. They'd need new silicone to mess with the motion estimation algorithms. Furthermore, these algorithms have nothing to do with the human eye afaik. What an ME does is it computes the similarity between a block in frame x and the same block and others around it in frame x+1. It doesn't analyze the whole picture for that and as long as a block on a different position than the root position doesn't have a lower similarity then the block stays right where it is (and motion vectors tell you where a block go). You would considerably increase encoding time, lessen coding efficiency (many DVD-9s are full even today) and I don't know what else if you were to tamper with the ME so I have my doubts that anyone would even wish to go into that. Imagine a maker of a hardware encoder being asked to make a less efficient, even stupid, encoder...

I'm a total newbie but it sounds to me that you think it will be a while before the studios put serious effort into designing DVD's that DVD2ONE won't work on? Forgive my ignorance but I'm thinking of purchasing the program b/c ReMpeg only works about half the time for me and I haven't figured out CCE yet (and don't think I'll be able to!) DVD2ONE is about my only solution.

Changing DVDs to be resistant to DVD2One would have further repercussions. Many of you may not realize this, but cable networks (like TNN and Fox) use DVDs now for movies, and they transcode them to reduce the bitrate using the same algorithms as DVD2One. What a mess that would be if the commercial DVDs were not suitable for broadcast use.
