• The Mac-Forums Community Guidelines (linked at the top of every forum) are very clear, we respect US law and court precedence when it comes to legality of activity.

    Therefore to clarify:
    • You may not discuss breaking DVD or BluRay encryption, copying, or "ripping" commercial, copy-protected DVDs.
    • This includes DVDs or BluRays you own. Even if you own the DVD or BluRay, it is still technically illegal under the DMCA to break the encryption. While some may argue otherwise, until the law is rewritten or the US Supreme Court strikes it down, we will adhere to the current intent of the law.
    • You may discuss ripping or copying unprotected movies or homemade DVDs.
    • You may discuss ripping or copying tools in the context that they are used for legal purposes as outlined in this post.

QuickTime Player does not play my video

I just downloaded a movie from torrent, after trying to open it, a message is shown saying "The document “movie.avi” could not be opened. The movie is not in a format that QuickTime Player understands." But the format is .avi. Is it not the default format for QuickTime Player?

I'm thinking that downloading a movie from a torrent...may not be something we care to discuss around here!

.mov and .avi files are containers for the video and audio that make up the movie. The video and audio can be produce by many various codecs. So, you can have two different .avi(or .mov) files that are produce by two different codecs. Quicktime may play one, both or none at all, depending on which codecs Quicktime recognises.

Avi files are not the default format for Quicktime. Mov/mpeg4 files are.
