Since a few people seemed to be having trouble loading your guide I thought I would give it a try. If I load it in a browser it does seem to take a very long time to load, but it loaded up fine for me in my Simple Client PVR.
Great job on your guide, it's nice and full!
When it did finally load in a browser I noticed a few channels that need to be tweaked in your ren file:
I285.65342.schedulesdirect.org:Investigation Discovery HD
I286.60468.schedulesdirect.org
estination America HD
IWatch.61458.schedulesdirect.org:Watch (here's another one for that channel: I245.61458.schedulesdirect.org:Watch
I565.46710.schedulesdirect.org:Hallmark Movies & Mysteries HD
I312.11221.schedulesdirect.org:Hallmark HD
I333.14873.schedulesdirect.org:IFC HD
I557.16108.schedulesdirect.org:Sundance HD
