It has nothing to do with bandwidth. The UI is rendered on the cable box. It's all about the firmware in the box.
Haha I didn't watch any TV. I was staying with family and in the evening they would be watching TV and I could not help but notice the horrible UI. I was soaking up the beautiful evening weather outside.
In fact, the lack of recordings on my DVR when I got home has made me rethink that fact that I pay almost $100/month for TV and I've been looking into other options.
