• 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.

I am using a Sony video camera for video capturing. As I transfer my videos into my iMac, quicktime player does not play them. It says something like this: "The document “123” could not be opened. The movie is not in a format that QuickTime Player understands." The format of the videos from my cam is MPEG.

How do I fix this? Thank you so much!

Either try playing it using VLC, or transcode it to a compatible Quicktime format using Handbrake.
