I'm not sure the lack of local retail competition really impacts product
selection available to us. Inconvenient, sure, but I don't think you can
make the case that manufacturers are innovating less because BestBuy has
become a lazy, dominant retailer in the US. (And on tenuous ground,
according to recently released financials.)

That depends on when you look. Boxee hit the market at $200 and can be
found now for $150. Google TV was $300 and eventually got marked down to
$100. Neither had local storage. Then Roku has had players for under
$100 for a while. (A bunch of "no name" players can also be found for
under $100.)

Also Vuze.

My understanding is that DLNA treats the DVR like a passive provider of
read-only media. If that impression is still accurate, that's a less
than satisfying way to interact with your DVR. Can you delete programs?
Is there any support for higher-level concepts, like marking a show
watched, or not? Bookmarking positions? Scheduling? Commercial skip?

It may be that this functionality can be added to DLNA, or implemented
with a protocol that operates along side DLNA, but either way there
needs to be an open protocol for remotely controlling a DVR. Something
that avoids the architecture mess that results in a MythTV client
messing with the back-end's MySQL tables.

I think you are chasing an obsolete problem. This thread started with
the question, "Is MythTV dead?" and my answer was that *all* DVRs are
dying. DVRs are past their peak with mainstream audiences.

If you are in the minority that needs the DVR-like control of your
programming, you'll just have to put up with the inconvenience that
comes with being out of the mainstream. Your best hope for an easy
solution in the future is some sort of "DVR-in-the-cloud" solution,
assuming that some company can successfully negotiates the necessary
licensing deals to avoid being sued[1] by the TV networks and the MPAA.
(The cloud music services cropping up lately provide some precedent for
this possibility.)

True.

Recent stats show that consumers are actually buying TVs more frequently
than they used to. On the scale of about 3 to 5 years, similar to the
frequency of personal computer purchases. This has been attributed to
the combination of ever increasing screen sizes (buying a new, bigger TV
for the living room and moving the old one to the bedroom) and falling
prices. (Perhaps the new OLED TVs will spur another wave of upgrades.)

This will lessen the major concern about obsolescence of IP TV hardware
built-in to TVs. Plus there will be a spectrum of other solutions, from
TVs with upgradeable firmware (some have this now), to bundled and
replaceable hardware (like the latest Roku player that's the size of a
USB Flash drive). Who knows, maybe the industry might even agree on a
standard for a CableCARD-like hardware module that can be upgraded.
