Thanks very much o to Mark, RDA972, and Jude.
Please accept my thanks , for give to me some attention. I will remove all codecs from one of the machines, and re trial the import/edit. . If will be ok , so i will talk to my business partner, in order to update our workstations . PPro, past CS5.5, have new features like adjustment layer, dolby support ( AA -CC2014), that we are need to have here. Maintaining PPro, AA, and the rest of adobe suite, will save a very costly NLE change.
Best regards,
Leonardo.
