Hi, I am following up on this article but have not yet tried it yet, is this the article you have been following?

MONOGRAM AAC Decoder 0.9.5.0Sunday, April 20th, 2008 Posted in Free Software | 17 Comments »

Hey, yet another small fix. Thanks goes to clsid for reporting this bug. Output of the decoder got screwed when output mixing was active and you switched audio streams with different number of channels. Download : mm_aac_dec_0.9.5.0_bin.zip (280 KB) Igor

The sound issue has something to do with the AAC audio stream being passed between DVBSBridge and MCE.

It seems that MCE isn't correctly interpreting the audio stream as an AAC audio stream. I have had spasmodic audio get decoded correctly so I don't believe the issue sits in MCE. The Fiji beta also decoded AAC audio just fine.

AC3 audio passes through exactly as it should, therefore TV3 is just fine.

I suspect DVBViwere or DVBSBridge is somehow messing with the timing of the audio stream.

2 possible ways to fix:

1. Alter the registry to enable the Cyberlink audio codec to see if that has a better time with the "modified" stream.

2. Figure out why DVBViewer is changing it in the first place...

or hope they modify the other dll to allow MCE to see HD channels again...

Still work in progress...

I have managed to get dvbridge to work with vmc, with sound on all channels (fresh install of Fiji and all other programmes). The new problem is the sound is not sycronised with the picture. It also does not record with sound. I will watch some other blogs to see if this can be solved.

Just a guess but I bet a you a dollar the sound is coming from DVBViewer and not Media Center.

Thats why its out of sync and doesn't record. If you turn down/mute the volume in DVBViewer the sound sync issue should be solved ie you'll be back to no sound at all...

I haven't had enough time to investigate too much further but so far I have worked out:

1. AAC is not being passed correctly from the DVBSBridge psuedo tuner. That is the problem is not in Media Center. You can confirm this by tuning into the DVBSBridge using another program other than Media Center. I still haven't worked out whether DVBViewer or DVBSBridge is at fault. At the moment I suspect its DVBSBridge, as DVBViewer correctly decodes AAC audio, and its simply passing the TS stream through to DVBSBridge.

2. AC3 audio passes through correctly ie none of this problem would exist if TVNZ would simply get their brown stuff in order and broadcast AC3 sound like they should be. ie for TV3 simply select the AC3 channel, and send that to DVBSBridge, as long as you are using AC3 filter or similar you will get perfect picture with sound.

Guide merging works just fine as well, which gets around the now next issues.

The reason H.264 was pulled from TV Pack was that we had a hard deadline and there was too many bugs in the H.264. Assuming whoever has managed to remove all the timebombs, still expect the experience to be pretty buggy.

Hi, I have tried everything for HD, so far the only option is dvbviewer and dvbsbridge and that has its own problems, still working on a way to fix it. Cheers

I have not yet tried dual tuners, however I dont think you can with dvbviewer from blogs I have read in the past. Have you got anything to work yet in VMC with DVB-T :) Cheers

no i had a feeling it didnt work dual tuner which makes me dubious about trying it.. really had hoped that the cracked H264 dll in vmc might have been the ticket to get it working natively.. might just go back to gbpvr.. unless anyone else has a way..

i wondered if its just the region setting in vmc as when i set to germany it does pick up 1 channel (although decoder error when i try to view it).. im kinda waiting for someone to say 'vmc with cracked dll in NZ still wont work because....' :|

No, it's just a matter that it's not ready for primetime..

The new GB-PVR (being tested now) has some cool new features.. While it doesn't have the same UI as VMC there are plenty of things it can do that VMC can't.

Hey thanks for the update Mike, although the original may be time bombed and there was a short time to develop, always keen to try it and find possible fixes, just for fun. Cheers

The reason it won't tune into NZ channels natively is that they have the HD flag set. The TV Pack after the beta was set to exclude these channels from the "active" tuning space.

When you attempt to tune into the NZ channels with the modified dll it still blocks the channels from appearing, even though MCE can actually see/decode them. This is handled by another dll which is discussed in detail in the Green Button thread. I believe this was an intentional move by MS to fully remove h.264 support from the TV Pack. Unfortunately none of the guys who modified the beta dll have this problem, so they stopped there.

What the DVBSBridge mod does is remove the HD flag, and therefore allow MCE to see the NZ channels.

DVBSBridge is only single tuner. They are apparently working on a dual tuner version, but as others have seen there is currently no known timeframe for release.

thanks for your detailed reply.. makes sense.. thought i was so close :) would be fantastic to get dvb-t freeview working in vmc!

so we just need to get this other DLL cracked ... takers?? :)

thanks again for your answer, and answer to the dvbsbridge multi tuner question.. as a sibgle tuner solution does this work well?
