Tried numerous times to create a dvd with my creation in imovie and IDVD saying ( Multiplexer error) i dont have enough free disk space for encoding the remaining assets. Ive also tried updating with updaters from apple.com and when i go to install the updates it tells me i dont have enough free space to install it. What the heck am i doing wrong. I spent hours creating my slideshow and cant burn it. It did seem to burn one copy a couple days ago and the movie played very pixelated and jumpy. Now cant burn. Please help!!!
