Javascript tools for building something that looks like a cable program guide
<p>I am looking for some tools or examples of code to help me build something that looks and behaves somewhat like a cable program guide. The general idea is that this will be an administration UI to schedule assets on individual channels. Scheduled assets cannot overlap on any given channel.</p>

<p>I found at least one decent looking scheduler (<a href="http://dhtmlx.com/docs/products/dhtmlxScheduler/index.shtml" rel="nofollow">dhtmlxScheduler</a>) but I fear that it will not be flexible enough for me to tweak to my liking. So I think I might need a more generic solution that I can bend in the direction I need it to move.</p>

<p>I would hate to resort to Flex for this but it might be my best bet. Any suggestions are welcome.</p>
