Hmm. I didn't have any issues last night. I was able to watch several hours of Netflix from TiVo. The last time this happened(last week) my Netflix cut out right in the middle of watching something. But I had no problems on my TiVos last night. I still had access to the discovery bar, Amazon, Netflix, and Pandora.
