So, I tried using kernel 2.6.32.2 from http://www.kernel.org. I compiled 
it OK.

I still get an error with v4l-dvb :

Hi, 
AFAIK the card just tunes to the desired frequency, applies configured

filters (to select the desired station through its PID number), and handles the
received transport stream to the calling application. It's up to the lastest to
properly decode it. Check that the software you are using is properly capable of
decoding this kind of content.

  Eduard Huguet



Hi,

the problem isn't to do with playback as I have another type of adapter 
card that creates a TS, from the same mux, that is played back with no 
problem.


It seems that the problem only happens when using the Nova-T card.

DTT in NZ has services with 1080i video format, I'm not sure that there 
are many other places in the world where 1080i h.264 content is 
broadcast using DVB-T, hence I was thinking that this combination may 
not have been well tested.

I don't know how this it works in NZ. Here in Spain there is at least
one station (TVC's 3HD) emitting HD content through TDT, and it works
flawlessly with a Nova-T 500 (as I have one). I'm not sure if contents
are 1080 or 720, though.

There were some problems watching these channels through MythTV, but
they were definitely decoding related. With current MythTV trunk they
are fine.

Anyway, as I said before, theoretically a DVB card doesn't know what
kind of streams contains the signal it tunes. Decoding  parsing is
handled by the app.

Maybe it's a problem of tuner sensibility. Is the low noise amplifier
(LNA) activated for the Nova-T card?

from the Nova-T card. My thinking is that it was probably not conceived
for
dealing with dual h264 streams.

Has the PCIe HVR-2200 been tested with dual h.264? I was wondering if
this card might have better performance.

Thanks,

Hi,AFAIK the card just tunes to the desired frequency, applies
configured
filters (to select the desired station through its PID number), and
handles the
received transport stream to the calling application. It's up to the
lastest to
properly decode it. Check that the software you are using is properly
capable of
decoding this kind of content.

Hi,

the problem isn't to do with playback as I have another type of adapter
card
that creates a TS, from the same mux, that is played back with no
problem.

It seems that the problem only happens when using the Nova-T card.

DTT in NZ has services with 1080i video format, I'm not sure that there
are
many other places in the world where 1080i h.264 content is broadcast
using
DVB-T, hence I was thinking that this combination may not have been well
tested.

Thanks,

Lou


I don't know how this it works in NZ. Here in Spain there is at least
one station (TVC's 3HD) emitting HD content through TDT, and it works
flawlessly with a Nova-T 500 (as I have one). I'm not sure if contents
are 1080 or 720, though.

There were some problems watching these channels through MythTV, but
they were definitely decoding related. With current MythTV trunk they
are fine.

Anyway, as I said before, theoretically a DVB card doesn't know what
kind of streams contains the signal it tunes. Decoding  parsing is
handled by the app.

I'm not using MythTV or any other type of Media playing application.

In any case, I see very different performance between the two different
types of card, when presented with the same input.

I'll gather some more data, if I can draw any new conclusions I'll update
the list.

Best,

Lou





Maybe it's a problem of tuner sensibility. Is the low noise amplifier
(LNA) activated for the Nova-T card?

That's something I hadn't considered. I'll check but I thought that the 
LNA was only applicable to the Nova-TD 500 (which has 2xRF inputs)?


Does the Nova-T 500, with only a single RF input have the LNA?

Thanks,

Lou

I don't know about the TD, but the regular Nova-T 500 definitely has a
LNA that must be activated, that's for sure :D...
