Q: I can't record 4 or 5 finger gestures! The app "goes away" / it zooms out / It performs some other thing on my iPhone/iPad.
Check that Multitasking Gestures is disabled in General Preferences on the device. If you do not, then the iShowU Gesture Recorder will not respond to some pinch & swipe gestures & four/five finger swipe's will cause the app manager to show.
You really want this option off to get the most of the iShowU Studio Gesture Recorder.
Q: The gestures appear jerkey / aka: not smooth, in the iShowU Studio preview.
Make sure you have a good network connection. The app sends gestures over the network, and bad/slow/intermittent wireless networks can cause poor recording performance.
