There is a complete code rewrite in the works for the logo generation code to improve logo retrieval performance (i.e. generating times, faster loading). Although it's fast loading already, there's always room for improvement. Once I'm done, I'll load it in to the forums for beta testing before final release, in which I will then release the source code for public use, with support via PM, for use on your own websites.
In the interim, I have fixed the scheduling in the logo so that it follows TWC's programming schedule as of September 27th.
Let me know if logo related issues come up, i.e. blank image, errors pop up when you load the URL directly, etc.
