I can pick up 9 channels from two broadcasters. Some radio and some TV, but I'm not getting picture on anything. Maori TV has fantastic sound, but as I just said, no picture. Can anyone pick up any picture or is my tv card busted?
I'm using the following info in Linux

T 706000000 8MHz 3/4 1/2 QAM64 8k 1/32 NONE
T 778000000 8MHz 3/4 1/2 QAM32 8k 1/32 NONE

And using scan, I'm getting the following TV list

What TV software are you using?

If you're using Windows at present only GB-PVR with the PowerDVD H.264 codec and DVBViewer are capable of decoding the H.264 picture that is being used in NZ. Most other TV software can't decode the H.264 video as MPEG2 is the norm for DVB-T transmissions overseas. You mentioned you were using Linux to get that info - Steve from OpenMedia will no doubt be able to help you with MythTV stuff as I haven't played with it for a while now.

The TVNZ MUX is also hidden at present so you won't pick that up with some software either.

Yes it is I..

As I mentioned over on dtvforum you need to take a look at my threads at http://www.mythtv.co.nz

The standard scan tools don't setup the VPID's correctly for H.264 video.

Also note that at the moment the video won't play in mplayer anyway due to the intelaced variant of H.264 they are using.

Hmm cheers, will check out the software mentioned.

I'm testing with both Windos and Linux (Ubuntu 7,10).
I have downloaded one of BBC's test clips 1080i H.264 and it plays (ever so badly but still plays). I also have a cople of 720P H.264 that play nicely. I'm basically getting "No Video" when trying with mplayer. If it was missing a codec, it would say so.
I basically just need to know if anyone actually can get the picture in order to know if the video card is busted or not. I have a DTV2000 H. I have not found a way to tell the tuner to use the antenna connector so that does not work either in Linux (but in Windos, the driver can set what antenna input to use).
Apart from mplayer, I have also tested with kaffeine.

That's why video isn't working. The interlacing that is used here just isn't part of any of the free codecs out there.

Got one step closer yesterday.
I recorded some of the data stream and was able to get the odd flicker with picture. You are most likely right about the Coded. I though ffmpeg on Linux could handle it as it support h264 and various variants. But after some more digging it is still missing some parts. It looks like the current cvf of ffmpeg support it so I will try to compile and test it over the weekend.

If anyone out there already have it working on linux or windows please point me to the codec (not just the package or software as they tend to include tons of codec…) and I can try to use it on Linux (that support dll etc...)

As I mention it detail at http://www.mythtv.co.nz the interlaced variant of H.264 they are using hasn't been implemented in either of x264 or ffmpeg at this stage. Hence the playback issues under Linux.

Linux users had quite a bit of trouble with the UK Crystal Palace trial as well. As it stands now the best two options are GB-PVR with the Cyberlink H.264 codec installed (you need PowerDVD Ultra) or DVBViewer however there do appear to be some audio issues with this software however since audio is not being transmitted on all channels at present anyway.

Good day all,

Sort of on topic. I am out in Paraparaumu and have never bothered with Terrestrial TV since moving in. With the forthcoming advent of HD on Freeview though I may change so can anyone please advise on what is the Tx for the Kapiti area.

Thanks

Where in Paraparaumu are you located?

The Ngarara site (Waikanae) will be transmitting the DVB-T signal and for most people this will probably be the best site for them.

sbiddle,

Thanks for that, I am just off Regent Dr. Being a UK import I was unable to correlate Tx names with locations but even I know where Waikanae is ;)

Just wondering if anyone on my side of the cook straight has had any luck recieving signal from Mt Kaukau.. Im in blenheim and will be hoping to lock onto it from here.. Ive been informed over at the dtvforum it has been sucessfully done but am wondering if anyone else has had success and if so where in marlborough they got reception with what equipment.. i dont have the equipment or knowledge for that matter to test it myself yet but yern for HD when it is launched.
