TiVo Stream to iPad Freezes

I just purchased a Roamio Plus. When I use the TiVo iPad app with its internal TiVo Stream, I get occasional "lockups" or "freezes" where play stops with a still frame remaining visible on the screen. It never starts back up. I have to touch "Done" and re-initiate play to get things going again. Just hitting pause and then play doesn't fix it.



Anyone else have the same problem?



I have not found this problem to be reproducible at any particular point in any particular program.



Might it be a network problem? I use an Actiontec router from Verizon FiOS for WiFi. It's also a MoCA router. AFAIK, the network is working fine, and the iPad app's broadband speed test shows excellent bandwidth numbers of over 30 Mbps.



I have to assume there is some "hiccup" somewhere that triggers the lockup. I wonder if some of the technically inclined contributors to this forum have any suggestions as to how I might figure out what is really going on?



Thanks.
