On my Powerbook 800 1GB, OS 10.3.3, I have been using Cleaner to compress my DV file for download. For the same category (large download) the Windows Media result is consistently better quality (very watchable in all screen sizes) than the QuickTime result. I get a occasional artifacting washing across frames in the QT movie (unusable). There are no errrors reported after compressing. I would have expected the opposite: ie QuickTime to be superior. Any ideas? (I have not tried Compressor yet.) PJ
