[LAU] Praxis LIVE screencasts / good screencast software for audio?

Hi All, Firstly, finally got around to some screencasts of Praxis LIVE in action - http://praxisintermedia.wordpress.com/2012/07/30/video-rough-cuts-1/ These are just 'rough cuts', unedited except titles and no voiceover. Only first 2 have audio, and the audio on the second is a little off in places (see below!) Secondly, anyone got a suggestion for screencast software that's good at glitch free audio? These are done with Kazam. First is mostly OK, but the second is a little glitchy. Finding only about 1 in 4 captures is any good - all sorts of weird glitches and sometimes speed issues, though the audio playback while recording is fine.
