Hi Def - HD Homerun?

Having bought a bloody great big TV, I see the point of HD (or more
particularly I see the jaggies in SD).

No more room in the backend, having already 2 PCI DVB-S cards, so
thought of an HDHR. Whats everyone's experience?

I see it has two tuners, presumably you can do multirec?

How are the channels distributed on the DVB-T multiplexes?

Any other hints/advice?

The specific model seems to be:

Hi Nick
That seems a new case! Be aware of the
http://www.hdhomerun.co.nz/hdhomerun/hdhomerun_tech_brief.pdf fancier
version that is in the older form factor that a number of listers have.
I've used mine more as a live tuner than for myth TV and have also
used it on holiday with a router and notebook to watch TV on a mythbuntu
notebook, over 802.11g. 576i always worked and 1080i worked most of the
time, a N grade router might be better.
I understand multi rec is fine.
Also note http://www.hdhomerun.co.nz/support/hdhomerun/instructions/
including the development guide.
I wrote a php app on the LAN to control the channels and volume and
direct the stream, it basically works however it needs a tickle up to
iron out some subtle bugs and is now out of date with the recent channel
changes, it used a .asx file to open VLC on the client PC. The
intention was to run it from an android phone as well for remote control
of a separate PC, I've not yet got TV showing on a Galaxy S2 from the
Hdhomerun but expect that should be possible too now!
The cost is expensive compared to other card options (when you have the
space!) however they give excellent IRC support and there is a steady
stream of firmware and software updates that no other tuner product can
match that I've seen. The Hdhomerun manual client software ("Config
GUI") is also a default mythbuntu inclusion. Its also good for testing,
seeing what channels are currently on the various channels! e.g.
firmware uploads and new channels.
I hope that wets your appetite enough?!

I have a HDHR, and it works flawlessly. No complaints.

> How are the channels distributed on the DVB-T multiplexes?

There are three: TVNZ, Mediaworks and Kordia.

I'd have to double-check but IIRC TV1, 2, U and 7 are on TVNZ; TV3,
3+1, FOUR and C4 are on MediaWorks, and everything else is on Kordia.

The Tech version I understand also includes screw on antenna, not the
plugs that are inclined to come out - and having two antenna inputs
allows separate tuner inputs - e.g. cable and DVB-T

Just adding USB DVB-T tuners would probably be easier (and cheaper).
There is one dual DVB-T tuner available that I know works, the Kworld
Dual DVB-T TV Stick (DVB-T399UR):

http://www.trademe.co.nz/Electronics-photography/TVs/Other/auction-382636244.htm

There are also $30 or so single Kworld USB DVB-T TV Stick II
(DVB-T395UR) tuners that work too - cheaper to get two of these than
one single dual one:

http://www.trademe.co.nz/Computers/Peripherals/Other/auction-382866923.htm

I have a dual and two singles of these.

If you want USB DVB-T tuners that have support in older kernels, I
have two of these (Pinnacle PCTV Nano Stick) and they work well:

http://www.trademe.co.nz/Computers/Peripherals/Other/auction-381600127.htm

http://www.trademe.co.nz/Computers/Peripherals/Other/auction-382092378.htm

I prefer them to the Kworld ones, but they are rather more expensive.
I use them on my main MythTV box, and the Kworlds on my laptop when I
am away from home.

This is the channel distribution from a recent scan of the Wharite
transmitter in the Manawatu:

Frequency: 690000000
TV ONE
TV2
U
TVNZ 7

Frequency: 706000000
TV3
FOUR
TV3 PLUS1
C4

Frequency: 778000000
Maori Television
Parliament TV
Trackside
ChineseTV
PRIME
TV33
Stratos
Radio NZ National
Radio NZ Concert
BaseFM

There are a few more "ghost" channels that show up in the scan but do
not work (tvCentral, TV-Rotorua, Info-Rotorua), and some ones that
appear and disappear for use in updating MHEG and FreeviewHD box
firmware (Homecast SSU and MHEG IC Test Channel are present at the
moment).

You need three tuners to record from all multiplexes at the same time,
and I find that I am needing all three tuners about twice a week. But
then I record far more than I am ever going to be able to watch.

You also need to consider more hard disk space. The HD recordings
from TV One and TV3 take up 4.8 to 5.3 Gibytes each for one hour with
4 minutes of post-roll.

I now have an HDHR, thanks to a list contributor :)

I can see instructions on the mythtv wiki, but are there any
instructions peculiar to NZ?
