DVB-T in New Zealand

Here's the log in any case.

This is pre-patch..

I suspect that patch might correct it for you.

can you choose the audio stream for alll stations or just tv3 ?

Would that be on playing or recording.

I just looked at the native log after playing the stream, and it was certainly cleaner looking (no AAC messages), but since I at work, I can't hear the audio - duh... I'll check properly tonight..

TV3 was the only one I noticed with two audio streams...

Playback.

Ok - I've just today grabbed a Silentpipe ][ Gigabyte Gforce 8600GT 512mb Video card to see how that helps in my HTPC - If my office pc is anything to go by this card should take over most of the cpu utilisation - Basically my office pc stays under 5% playing H264 with the same card (Same but with only 256mb). I'll report back - This card is fairly cheap these days (theres one for a buy now of $172 NZD brand new right now on Trademe) so it could be a good "upgrade" path for people wanting onto the digital band wagon. The test recordings I've done look exceptional on my 37" LCD where recordings in medium quality standard def MPEG2 look a little blocky and washed out so I'm looking forward to going full digital - If things work out I'll get a 2nd Nova-T 500 to give me 4 digital tuners - My next problem will be whether the hard drive throughput can keep up with 4 digital streams recording and still be able to playback - Its rare I record 4 channels at once but it does happed the odd night at crossover times. I might have to build a dedicated recording server and then just have a playback pc in the lounge with a Gigabit link.

I also have noticed the audio was out of sync for TV3 - at least on playback of a recording (havent sat down and watched TV since).

When i do a scan of the DVB-T in canterbury - i do not get 2 choices of audio for TV. (i have seen this option on some sats like TGN on D2).

Possibly this is pre-launch issues? - maybe after 'going live' tonight (i think today was the date mentioned) all the channels will be ok.

I've discovered the problem for my audio crackling and stuttering problem (out of sync on a faster computer?). It even happens occasionally with interlaced channels where cpu usage is only about 50%.

After much trial and error I got TV3 to show in graphedit (ended up having to load a recording with the GBPVR ts reader to get the correct output pin types for the demultiplexer) . It turns out crackling happens when the mpeg 2 demultiplexer is the clock, it works perfectly with the audio renderer as the clock (probably a monogram aac issue).

I found a setting in config.xml called ForceAudioReferenceClock which sounds like it should do this in GBPVR but it doesn't seem to work, or is this something unrelated? I can't check because the add to ROT registry key doesn't seem to work. Is it possible for a patch for this clock problem? I think it is a one liner from the brief look I've had at directshownet (I was thinking of coding a small tv app after discovering this but put it in the too hard basket for now ).

Also one other issue: zoom settings don't seem to work with EVR (for overscan). I have to use EVR as the cyberlink decoder seems to accelerate only in EVR on Vista.

Anthony

If you set ForceAudioReferenceClock to 'true' it should use the audio renderer as the clock. If its not, then post the logs and I should be able to tell if it is trying to do this.

This is a limitation of EVR. It cant accept aspect ratios with values outside of the 0,0,1,1 range.
