was able to use ffmpegX to change the file to a dv
file. However, now the file is huge (15GB) and
imovie won't let me import because of the size..any
suggestions?
You are doing this the hard way, but you can finish what you've started by placing the DV file in iDVD and let it create your DVD. You don't need iMovie.
The easy way would have been to get either Toast 6 or Toast 7, drag the AVI to the Toast Video window and click the burn button.
With ffmpegx you could have converted the file to MPEG 2 and authored as a VIDEO_TS folder without converting it to DV. Once you have a VIDEO_TS folder you could use DVD Imager to create a video DVD image file to burn to DVD using Disk Utility.
I previously mentioned that there is good advice for working with AVI's at the Mac forum at
http://www.videohelp.com . You should spend some time there.
Alternatively, you could buy an inexpensive DVD player that has Divx AVI playback capability and burn your AVI file to a data CD. This should play without any conversion at all.
