a lot of us are sourcing these movies but are they really true hd?? most of my 1-2 hour films are 10-15gig so theyre obviously a lot higher quality than standard dvds. but how are they encoded for the american airings? obviously they are just the same film shot with the same cameras but encoded at a higher rate. but is this really hd?? as its not shot with the new cameras? Also how comes all the old films like clockwork orange can be found in hd??
