Hey if you figure out some way to hack it to extract the recordings to a PC let me know. I might just jailbreak mine just for that.

After poking around the iOS directory, I have found where the video downloads are stored on the iPad.

The TiVo app itself is called "Quicksilver.app" in the internal directory. (I see some references to "Quicksilver-TiVo.") And in its enclosing directory is a "Documents" folder, and in there is a "SavedVideos" folder. I just don't know what to do with what's inside; it's a bunch of .seg files:



I am saving this folder to my Mac now to see what to make of it.

In other news, I am using a great jailbreak tweak called UnrestrictPremium 2, that allows for AirPlay Mirroring to work on apps that otherwise restrict it.

Indeed, it is now working with the TiVo app. :up: (Also works with many others that have the same crippling, like HBO GO, DirecTV, TimeWarnerCable Live TV, etc. Very happy to have this, it opens up doors!)

This tweak lessens my desire for a TiVo Mini, quite frankly, since I now have a TiVo Stream and an iPad, playing back on a bigscreen TV (via AirPlay Mirroring and AppleTV.) No HDMI cable or other tweaks required.

I suspect the remote UI would be a little better with an actual TiVo Mini, and the video would certainly fill the entire screen (whereas AirPlay Mirroring like this, for me, leaves a big black border.) But still, this is free (have we heard yet if TiVo Mini has a monthly fee?) and feels great to be able to bypass the annoying anti-AirPlay-Mirroring measures that these apps have been instituting.

Interesting. Based on what little I could find poking around the systeminfo screens the Stream uses HLS for streaming. HLS breaks video into small segments so you can randomly access any portion of a video while it's streaming. It would appear TiVo retains the HLS segments in the app folder for local playback. HLS segments are really just TS streams so, provided they aren't encrypted, you should be able to play them in VLC. If they aren't encrypted you should also be able to join them all back into a single file using VideoReDo.

Is there a way to roll back the OS on an iPad? I just got a brand new iPad3 today. However I already upgraded my iPad2 to iOS6 yesterday (didn't expect the 3 until next week) so I have to upgrade the 3 to iOS6 to use my backup. However when I'm done and sure everything is working I'd like to roll the iPad2 back to factory defaults and then JB it. Is that possible?

It looks like it is possible if you have the blobs saved. Here is a blog entry from the dev team: http://blog.iphone-dev.org/post/31869383801/blob-o-riffic

I looked at them in a hex editor. They don't match any format I've ever seen, so my only guess is that they are encrypted.

From what I understand HLS uses SSL encryption, so that could explain the seemingly random data. I was hoping that maybe TiVo stored the local copies unencrypted or converted to the standard TiVoToGo format, but that doesn't appear to be the case. TTG files are encrypted but only the video and audio streams are encrypted, the container is still a standard TS or PS. These files don't seem to have any discernible pattern to the data which means the entire stream is likely encrypted.

That doesn't bode well for the possibility of side loading capabilities coming to TiVo Desktop. I think our only hope of seeing this on a PC is via a Win8 app that is completely self contained like the iOS app.

I tried pretty hard a while back to reverse engineer MRS but had very limited success because of SSL encryption. Would be great if someone much more familiar with SSL MITM attacks or the like to continue that work:
MRS Discovery Thread

I keep hoping the so-called yet to be released to public new SDK may have hooks in place for streaming to and from series 4 units but I'm not holding my breath on that (or even that it will be publicly released to anyone but TiVo partners).

The disconcerting poll data on reliability notwithstanding, I decided to give it a try.

Got the last Stream at the local B&M Best Buy. Got it home, attached it to the network, found it in the TiVo iPad app and went through the update cycle.

After five or so reboots, I'm stuck on activation, because TiVo's website has the relevant account maintenance page offline...until tomorrow. I'm waiting now in chat and, for some reason, moving backward in the queue.

After about ten minutes, I got through to [TiVo RightNow CSR], who tells me that the requisite system is offline and helpfully suggests that I wait until tomorrow to set up the Stream. ("No activation for you! Come back one day!") This is an excellent idea, except that the reason I went out today was (1) to install the Stream on the weekend when I actually have some free time, and (2) so I can sideload some stuff for the trip that I'm going to take tomorrow.

The fun thing is, I'm afraid to kill the TiVo app on my iPad due to the anecdotes here about how brittle the initial setup process is.

Oh, goody. TiVo sent me a survey request. Five points for [TiVo RightNow CSR] and one point and a "Not Likely to Recommend" for the overall experience.

This is just a stop-dead issue for a new Stream, right? If some poor schmuck talked his parents into getting a TiVo Premiere, he's not sitting there with an M-card trying to explain that his folks really don't want to go back to the &*@Q!%# Time Warner box, is he?
