I use Plex, and I know basically what they're talking about. They're talking about their version of Theater View. A a fullscreen, remote-control enabled mode of the Desktop app for Windows.
I've never used it. I use Plex nearly-exclusively for mobile device playback (iPad and a tiny bit of iPhone). The handful of times I've used it from a computer, it was my laptop hooked up to a hotel or friend's projector or whatever, and I've just used the web interface. You have to use a mouse to control most things, but on my laptop that's rarely a big deal.
It isn't really surprising. As they said, I'm sure the vast majority of their users just use TV-connected pucks of one variety or another.
There's an opportunity here. You'd be a lot better positioned to take advantage of it, IMHO, if
a few issues were addressed. Still, I do think JRiver could capture some of the fleeing HTPC users. MC works quite well alongside Plex (that's exactly what I do). You can:
* Use all of the tools and organizational prowess of MC to manage your media (which Plex doesn't provide at all and you have to do it like an animal).
* Theater View for your HTPC(s)
* MC is hands-down better for music.
* Import the media folders from your MC Library into Plex to serve to mobile clients and any TV-pucks you have, and MC will let you "perfect" the file naming structure to conform perfectly with what Plex expects.
So, tell people that. You have some issues in mobile device support for video, but it works alongside Plex just fine. The only issue really is that watched status and position doesn't sync.
Overall, whether this turns out to be a good tactical move for Plex remains to be seen. Longer term, though, I think strategically they're probably right. I don't have one, and I'm not really in the market right now. But, the pucks have won, at least this round.
