I think I'll give it a go. Of course, I only want access to what I'd be subscribed to, so that's no problem. I guess if Surewest is encrypting/starts encrypting, I'll just break down and spend the big bucks on a few Hauppage HD-PVRs. It's disappointing to have to buy stuff like that to access the signal you're already paying for, but right or wrong, it's getting more and more difficult to avoid doing that.
I tried to talk to Surewest about it, but I didn't get too much information before they got nervous and didn't want to talk about it anymore. They confirmed they're supporting both the mediaroom approach and the old equipment approach, but that eventually everyone will be forced to mediaroom. My guess is that it's possible to get an unecrypted signal now, but when they have everyone on mediaroom, they'll turn encryption on.
It wasn't clear to me if folks that were on mediaroom now were already negotiating PKI keys. Docs on mediaroom I've seen talked about that and it sounded like mediaroom ALWAYS did that. But maybe that's an option for the provider that Surewest hasn't activated yet because they're still in their migration.
I also suspect there's a VLAN separating IPTV from the rest of the network. Thus why the MythTV wiki specifies a dedicated NIC???
Anyway, not much concrete information and so apologies if my guesses are all wrong.
I'll order Surewest soon and we'll see how this works out.
As an aside, bigRoN, if you're looking for a quick way to get Myth up and running, you can check out these:
You'll want a videocard that supports VDPAU.
