You probably really need the plug in for $20.
Hi, I don't know if we have/had the same problem... but i could not get my DVD into imovie no matter what I did... I had to get the latest Apple Quicktime and then buy for $20. (google it and buy it from apple)....the plug in called QuickTime MPEG2.dmg.... Now, finally, as I type this, it is loading into imovie after buying and downloading this... I tried everything, but I had to pay the $20.... Now I've got to learn to edit this without a book. I miss books, dagnabbit.... Good Luck!
