Still asking the question: Since DVD plays so nice yet downloaded video items do not and Dan told us that this was because the downloaded file had to be worked on a lot prior to showing on the screen, we ask this question:
Could a "good" server operator have done this processing for us and then downloaded the worked on file, so that the video would play just as good as a local DVD does? Keep in mind that these new $9 per month movie services may have done just this very thing, since no way will the consumer pay for a movie that is of the general quality that is downloaded from the web and shown using Quicktime or Real.

To clarify Bruce's post... This has NOTHING to do with the media format. CD, DVD, Blu-Ray... those are just media, plastic discs that basically emulate random-access r/o hard drives. It's the codec used to encode/decode the video and audio data ON the media that's asymmetric. The basic theory is that playback should always be easy, to allow use on less expensive hardware. They try to do all the number crunching, compressions, optimizations, etc, during the encode process, because that's when the "author" (home user or professional) is going to have more cpu power available. As to the primary codec used.... CD-Video is either MPEG-1 or MPEG-2. DVD-Video is MPEG-2. Blu-Ray discs use MPEG-2 or MEPG-4 (mostly h.264) or VC-1. Then there's those players that support DviX DVDs. DivX is simply a flavor of MPEG-4. - Dan. -- - Psychoceramic Emeritus; South Jersey, USA, Earth. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
