Hi all, Hoping someone can offer an explanation and a solution. I use a Mac Mini home theater, and have backed up all my DVDs to external drives and use eyeTV/iTunes for all content - meaning I have thousands of TV episodes, movies, etc...aliased into iTunes. Most recently, I'll add a video file to an external drive and alias it into iTunes. When I use iTunes to change the name of the TV show, add artwork, etc...I'll get the rainbow ball for a few seconds. At times, it gets to the point where I have to quit iTunes. Once I do that, the video file is unwatchable. The icon turns green, and when you attempt to watch it anywhere from a few minutes to almost the entire thing is all green and garbled. It's to the point where I have to make a backup of the file before I try and modify it. Also, I added a 12 gig file to iTunes over the weekend - the first I think that large, and the video playback was slower than the audio playback in iTunes. People walked in slow motion, but the audio was fine, so things got worse and worse the longer it went. In Quicktime there was no issue. Only when my computer was performing multiple tasks could I replicate the issue in Quicktime. Is this a sign that my iTunes library has grown too large? Is there anything I can do to fix this? Thanks very much!
