The second option isn't really doable, it looks like crap and breaks the
remote control experience as you usually need a mouse for that. The first
option won't work for all sites, but some sites will allow this. This would
depend on the terms of service. For instance, HGTV.com allows this. There
are other shows that would be considered "new media" that allow this such
as twit.tv (I am unsure about revision3.com allowing this, but since their
ads are in the stream they probably do). Further, these shows allow
downloads and offer RSS feeds for their episodes. I think dealing with
API's and feeds (eg. RSS feeds) is a must, because screen scrapers tend to
break. Lastly, what/how do we deal with users selecting a piece of content
on their tablet (like an online video) for displaying on their TV?

I think this is where plugins come in. If each plugin is required to accept
a search string and search it's specific content and reply with a valid
list of results, then we could build search into the 10' UI that would
query each of these and build a single list of available content search
results. This search may take a bit of time, so alternatively U1 could keep
a database of what shows are on known plugins (via a periodic check) and
offer that to the client, the client could then check the plugins that it
didn't get from U1 and also the local DVR. The user would then see a list
of search results that included the source (be it netflix, amazon, ubuntu
one store, youtube, DVR, etc) and video title and select which one they
wanted to watch.
We should also use sites to get information (info, backgrounds, fanart,
etc) on the content (eg. http://thetvdb.com/ and http://www.themoviedb.org/).
These sites were built for this purpose.

I talked with one of the Linaro guys at UDS and he said as long as it is a
gstreamer backend it was fine (which is why XBMC won't work), but I also
talked with Daviey Walker who said he has used XBMC on an ARM and it works
fine. Either way, I agree we need to use something that is capable on all
hardware so we can release an image rather than needing to purchase certain

Unfortunately in the US the EIT data is extremely lacking. We get somewhere
between 12-24 hours of data and it isn't 100% accurate (because it's up to
the channel to provide it can be a couple of minutes off causing scheduling
conflicts). It is an option, but I'd like to (rather) see support for
something like schedules direct or an offering from U1. If it is an
offering from U1, it is likely going to be data purchased from TMS which is
what schedules direct gets it's data from which is really good data.

I agree that we shouldn't require everyone to have a Myth backend, but not
sure we should build our own (which is more than just basic recording
functionality). We could do something similar to what XBMC is doing with
their PVR which is build plugins to connect to each type of backend
