• The forum rules at Mac-Forums (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.

Problems with imovie, wont save



So i just got my nice long project done in imovie that took me a lot of time to do. I went to save it and 8 hours later the thingy was still spinning, so i force quit it and a partial file was saved. It looked like ph.mov~ . Im using imovie 3.0.0 on a g4 800mghz emac with 512 ram. Ive never had this problem before. Does anyone know a fix for it? I dont want to have to start over.


Ok, now anytime i try to do anything in imovie it takes forever. It has never ran this slow.

I am just guessing her, but it sound like something is corrupted. You can try removing the com.apple.iMovie3.plist file.
