xvidcap users on Ubuntu Hardy Heron are in for a nasty surprise. The moment you press the red record button, the program greets you with a segmentation fault error (bug #224355). This isn't a serious problem but it does make users shy away from using the xvidcap tool.
The solution is to tweak few settings on the Multi-Frame preferences page. The xvidcap preferences page can be accessed by right clicking on the first button on the left hand side marked test-0000.mpeg .
