cSlider: stop autoplay on mouseover
How can I stop the autoplay function of cSlider with an onmouseover event?

This feature not implemented by default but this shouldn't stop you from implementing it on your own. Look at modified plugin code below (draw attention on stop and 'start' methods)
(function ($, undefined) {
/*
* Slider object.
*/
$.Slider = function (options, element) {
this.$el = $(element);
this._init(options);
};
$.Slider.defaults = {
current: 0, // index of current slide
bgincrement: 50, // increment the bg position (parallax effect) when sliding
autoplay: false, // slideshow on / off
interval: 4000 // time between transitions
};
$.Slider.prototype = {
_init: function (options) {
this.options = $.extend(true, {}, $.Slider.defaults, options);
this.$slides = this.$el.children('div.da-slide');
this.slidesCount = this.$slides.length;
this.current = this.options.current;
if (this.current < 0 || this.current >= this.slidesCount) {
this.current = 0;
}
this.$slides.eq(this.current).addClass('da-slide-current');
var $navigation = $('<nav class="da-dots"/>');
for (var i = 0; i < this.slidesCount; ++i) {
$navigation.append('<span/>');

$navigation.appendTo(this.$el);

$.fn.cslider = function (options) {

this.each(function () {
var instance = $.data(this, 'cslider');
if (!instance) {
logError("cannot call methods on cslider prior to initialization; " +
"attempted to call method '" + options + "'");
return;
}
if (!$.isFunction(instance[options]) || options.charAt(0) === "_") {
logError("no such method '" + options + "' for cslider instance");
return;
}
instance[options].apply(instance, args);
});

var instance = $.data(this, 'cslider');
if (!instance) {
$.data(this, 'cslider', new $.Slider(options, this));
}
});
}
return this;
};
})(jQuery);
With updated plugin you can pause and renew autiplaying with this code:
$('#da-slider').hover(
function () {
$(this).cslider("stop");
},
function () {
$(this).cslider("start");
}
);
