First up I am using a Nova T 500, and I have installed the latest wintv 7 cd 1.1d from the hauppauge website. My system OS is windows 7 RC (7100)

When using Wintv 7, the picture shows on every channel but there is no audio on any of them. I am using cyberlink h264 video codec and have tried various audio codecs to no avail.

When using windows media center the picture and audio work for the HD channels 1, 2 and 3. But for the rest of the channels the picture is black or green and pixelated - but audio comes through fine. I don't know how to check what video codec windows media center is using.

Does anyone know a solution to this problem?

EDIT: OK after restarting, wintv 7 won't even buffer any channel but windows media center is still as before.

Bump. Can anyone help me troubleshoot this? I really don't know where to go from here. I'm OK with wintv 7 not working, and would like to just get the video working on wmc.

NZ Freeview|HD uses an unusual audio format known as LATM-HE-AAC. Win7 Windows Media Center natively supports this format. However if you are using a 3rd party PVR application, it must be capable of detecting this audio format and splitting it out to a audio decoder that can decode this format. GBPVR and MediaPortal support this format along with requiring an audio decoder that supports this format, eg Monogram AAC decoder http://blog.monogram.sk/janos/2009/03/08/monogram-aac-decoder-0960/

When using windows media center the picture and audio work for the HD channels 1, 2 and 3. But for the rest of the channels the picture is black or green and pixelated - but audio comes through fine. I don't know how to check what video codec windows media center is using.

This is a known issue on ATI video cards with the current Win7 Catalyst drivers. I belive Nvidia video cards work ok.

Thank you so much for your reply. I do have an ATI card (HD 4850) and am using catalyst 9.5. That's a shame with wintv v7, I hope they add that support I think its a really nice and fast program. I am happy how far freeview has come along in terms of software support since last year when I gave up (got everything working on mediaportal back then but it was just too buggy!).

OK, I've just installed GBPVR and am using monogram AAC decoder. Picture is working on every channel, but there is no sound for every channel EXCEPT "TV3 (AC3)".

Doesn't sound like your monogram codec is not taking effect.

Have you registered it? regsvr32 mmaacd.ax

And then in the gbpvr config app have you set monogram as the aac and he-aac playback codecs

For some reason I have had monogram already installed as it appeared on the drop down list in both wintv 7 and gbpvr before I tried to set this whole thing up (and yes I selected it in the config app as both aac and he-aac). But I think it may be an old version that must have been part of some pack that I must've installed a while back before the new LATM support was added. I have not been able to install the mmaacd.ax from the site mentioned, however.

I put mmaacd.ax into C:\windows\system32 but when I try to regsvr32 it the following happens:

regsvr32 c:\windows\system32\mmaacd.ax gives me this error message: The module "c:\windows\system32\mmaacd.ax" failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary dependent .dll files.

regsvr32 mmaacd.ax gives me this error message: The module "mmaacd.ax" may not [be] compatible with the version of windows that you're running. Check if the module is compatible with an x86 (32-bit) or x64 (64-bit) version of regsvr32.exe. (By the way I'm running 64 bit windows 7)

EDIT: I also just tried running the commands under administrator rights but the error messages were the same.

ahh, yeah the 64bit windows wont help. I think there is a way of registering 32 bit stuff, or run it in compatibility mode. And you may want to take it out of system32 and stick it somewhere else and see if that helps.

I run 32bit xp

It doesn't let me run in compatibility mode "compatibility modes cannot be set on this program because it is part of this version of windows"

and If i try stick it somewhere else it says "The module d:\mmaacdx.ax was loaded but the call to DllRegisterServer failed with error code 0x800700005. For more information about this problem, search online using the error code as a search term"

Searching the error code doesn't help.

I guess there is still some work to do for freeview compatibility across the board with PCs.

catalyst driver version 9.6 just came out but I still have the same problem with WMC after installing it. Are ATI even aware of the problem? It's not even listed on the releaselog's known issues section.

Hi someone might want to know this. I purchased wintv7 HD software from the UK it cost under NZ$50 but seems to be much more user friendly than powercinema which is not so flash with vista x64. It is bundled with all the codecs h.264 & the LATM-HE-AAC codec. Users have to buy it or you will not get the audio support required - That's not hauppage's fault those codecs cost money. It's pretty good, click it and the TV starts - no fiddly navigation panel. BTW I have the nova t500 and the sound quality from all but C3 sounds really crappy, is that due to the tv card or the broadcast?

Does anyone sell the software in New Zealand? Or is there anywhere to buy the audio decoder online?

The only thing I am aware of is that wintv v7 HD is shipping with certain TV cards as a bundle here in NZ.
I rocked onto the hauppage site & payed by paypal to get the CD.
I am not aware whether you can get the audio decoder downloads, (that would be too easy!)

Is it this?

Might consider this...13.98 euro excluding VAT...that's quite reasonable actually.

Yes that's it, its worthwhile I thought. But IMHO there is still a way to go with HDTV on the PC. Would prefer it to be supported with media centre vista x64 native. (my wish)

Simplest solution in my opinion is Windows 7 version 7137 or later finds the Nova T 500 and all required without any add on Just setup Media centre and everything works. Then get Bigscreen Epg register and setup and evrything goes 14 days Epg Hd etc.
