When trying to encode a video file in lives 1.6.1 on opensuse 12.1 x86_64 Desktop PC, lives fails to open the encode video dialog box and starts using 100% of the cpu. This only happens on a cpu with more than one core. Also when opening a video file from hard disk it will also use 100% of cpu and you will have to click the cancel/pulse button to get lives to finally open the video file. This also only happens on a PC with a cpu of more than one core as it does not happen in a virtual machine with one cpu core assigned to the VM. My PC specs are as follows: Intel Quad Core i7 CPU, 4GB RAM, 1GB NVIDIA Video Card, Intel DH55TC Mboard, Intel HD Sound, KDE 4.7 (latest version shipped with opensuse 12.1).
