This is my first time using uTorrent and it generally was fine. I have been using Vuze for about a year. Currently have a MacBook Pro, Intel Dual Core 4MB ram. I also run Wondershare Video Converter for mac (v184.108.40.206) to convert avi files to mp4 to view via Apple TV. When I installed uTorrent, the video converter stopped working. It finally started working when I removed uTorrent. There seems to be an inherent conflict between the 2 apps.
