My purpose was to download a DVD that I could play back on my Power Mac system 10.8 DVD player application. Well, the feature film download which took almost 24 hours, and then it appeared to be a kind of Quicktime file. However, when trying to open it, i received the message that ...."you may experience difficulties trying to view the file since the required compressor (or plug in¿) is not available." When double clicking on the file on my desktop, likewize i get the message and the Quicktime viewer is missing in the Quicktime window; just the solid silver frame color through and through. Well, I checked the Quicktime website, and i have the most recent Quicktime from my Apple automatic upgrades anyways. Would 'Quicktime Pro' do the trick? Does anyone know a work around for this obstacle? Is there not a DVD format for movies anyways, and perhaps i just need to identify it in a file before I download it??
