That isn't Netflix's job. A post house delievers the raw .mov files to Netflix. The post house gets the files or tapes from the studio or whomever manages the libary for them (aka another post house). The post house has to comply to a set of standard's set forth by Netflix or it is automatically rejected. Most of the time things like no interlacing is in those requirements but also there can be exceptions if no other source material is available. iTunes works the same way. So say the post house that delievers to Netflix is only getting digital raw .movs and not the actual tapes, they may not be allowed to re-encode those or have access to the tapes to do the correct conversion.
