YTTV has what might be called a decent line-up in this age of lowered expectations. And it is great at figuring out how to inject commercials into content, slyly polling viewers on which sports teams they might be willing to pay extra to watch and starting you off with a triple-shot of commercials before seeing any of the selected show whenever you change channels.
But providing a proper channel guide appears to be more then they can manage. Shows are listed with incorrect titles. English language shows have Spanish language titles.
These things don't go on for a few days before being corrected. It's business as usual. We expect Google has the resources and expertise to fix this, and can only conclude it does not bother them to deliver a shoddy product.
