What's up guys, I got some videos on iTunes that I downloaded off of YouTube and when I try to create an iPod or iPhone version it will start converting for a couple minutes then usually when it's a 1/4 of the way through iTunes freezes and basically locks up my computer. I can still click the start button and restart, shutdown, or log off my computer. So my question is how to fix this and get the videos to convert, also do I need to just remove those videos and redownload them. Btw I downloaded the videos with the YouTube downloader thing if that means anything. Any help would be appreciated, thanks.
