Dear Greg and Neil, Thanks a lot for your clarifying answers. Yes, all the computers that I tested on with the HD version of the movie where kind of old and no more than one core for them. I myself have a quad core so of course it could play it well. I have just tested the MPG version on the old ones and it plays very well, so my problem is solved. And I understand and agree with you both about the explanations for the files to be the same size. And when I rendered in mpg I used Maximum bitrate and Maximum everything (8mbps of video) so the mpg file could have been smaller.
Just one more little question: on the mpg version I found that the faces of the movie shot originally in HD are a bit pixelated (it shows on the faces because they move, but I guess it is all the frame. You get to see horizontal lines when the faces move as if there were a transparent blind before them) , as if the deinterlace is done wrong (I guess). Could that be that I selected it in upper and should be lower? For the record is not the natural blurness that you see in a mpg video compared to the HD version, it's something else. Thank you all! 2011/6/29 BEDFORD NEIL <[email protected]> > Hi Greg, > > Been there, seen it, got the t-shirt.
