I recently replaced my Premiere XL4 with a Roamio Pro. I wanted to copy a bunch of recorded shows from the Roamio onto my iPad Mini Retina, and the behavior has been very flaky. Here's what I've seen.
I was at home, on my local Wi-Fi network with the iPad. The TiVo is connected to gigabit Ethernet. My router/WAP is the latest-generation Apple AirPort Extreme. AirPort and iPad are fully updated.
I chose about 10 shows to copy over. I chose "Best" quality for all of these. (Aside: why do I have to make this choice every time? I never want medium.)
The estimate was that it would take roughly 30 minutes for the first show to download, so I left the iPad awake and plugged in to power when I went to sleep.
When I got up the next morning, it had not downloaded a single show! There was a message saying that the TiVo (not the iPad) had lost connection to the Internet. Who cares about the Internet? This was a copy over the LAN. It had made progress on one show, but had apparently bailed due to the connection problem.
I quit the iPad app (dragged it out of the app switching view to force a true restart), then resumed the downloads. I left for work. Again, the iPad was plugged in to power and awake.
Got home, and a couple of shows had downloaded, but it had failed again. Two shows were marked as having failed, and I guess at that point it gave up, and the iPad went to sleep.
Upon waking the app up again, I noticed that the remote control icon at the top of the screen was greyed out, the way it would be if you were outside of your house and therefore unable to control the TiVo's on-screen display. I force-quit and relaunched the app, and this time the remote showed up as active again.
I resumed the downloads once again.
Some time later, I came back to find the iPad asleep again. All but two of the downloads had finished, but it was again showing the crossed-out remote as though it thought it was not at my house.
So, I did the force-quit dance again, and the remaining shows downloaded.
This is a really crappy experience. With my Premiere and the separate Stream box, I did similar downloads to the iPad on several occasions, and it was always reliable. I searched the forums and found a few reports of problems with the Roamio in this regard, but they seem isolated.
Have others had this problem? Were you able to find a solution? Why does the iPad app keep thinking that it is not on my LAN, and disabling the controls? The iPad was only about 15 feet from the access point with strong signal, etc...
