Downloaded the newest 3.3 earlier...could not use it to VJ longer than 15 minutes. Some process called VTDecoderXPCService was showing in my Activity Monitor. Spiked multiple times to around 146% CPU. Went back to 3.2...no longer had the issue. Running Mac OSX 10.11.6 El Capitan, 2GB dedicated graphics, 16 GB Ram. Never had this issue before now.
