never did comparison with US version..
care to explain what impact if the bitrate lower?
Possible issues would be softness (instead of a sharper image), slightly more artifacting/aliasing. Again, unless someone really messed up with the encodes, it would only be apparent in the very big screens and with people with discerning eyes.
However, when the encode is not done correctly or there are problems with the source, u would detect it easily. I hv seen moire, artifacting/aliasing, digital noise, EE and DNR on 1080p encodes. Theoretically, it shd be almost zero, but remember the source is film which is higher resolution than 1920 X 1080. Depending on how they transfered to 1080p, it is very possible to induce all the problems. All this is not even taking into account the bitrates.
In short, bitrates are not everything. Most of the time the encoding and the amount of effort spent in restoring the movie from the masters is where the problems lies.
