Video on demand issues

I have a Series 3 HDXL. Until recently, I have been able to receive the podcasts that I subscribe to without problems. I am hardwired to the network and there does not seem to be any problem with Tivo's daily connection. I no longer receive any podcasts and even have issues getting to the video on demand sub-directory where you can choose between Netflix, Amazon, or podcasts. I get bounced back to the main screen. I have rebooted without any change noted. Next I will try to pull a program from it with my roamio. I miss my podcasts.

Thanks,
