dobeman. How do you have your HD-DVD player hooked up? If you are using the Optical or Coax cable from your HD-DVD player to a Recievor, then you will need to make some changes in MF6 and they don't always work. HDV Audio is in a format called MPA or MPEG1 Audio which is two channel stereo. When your HD-DVD player outputs an authored disk from your HDV footage, it outputs the signal as MPEG1 which is not a compliant bit stream that can be used over an Optical or Coax connection from your HD-DVD Player. It does however work over HDMI (I can't explain that one). I have my Toshiba HD-A1 hooked up with the Optical to my Recievor and use the HDMI to my DLP TV. When I play a home made HD-DVD, I turn my recievor off and play the audio through the TV. It works fine, just not real loud.
This totally sucks. You have two options:
1. Set the audio output of HD-DVD player to PCM. This will convert internally the signal to a compliant BitStream 2 Channel PCM track that your recievor can play. (In my case this is not an option because the HD-A1 is a slow turtle and to change the audio output takes like 10 minutes).
2. Click the settings tab in MF6 at the bottom and click the MPEG Settings. In the compression tab, click on the audio and change from LPCM or MPEG to Dolby Digital.
When I first picked up MF6, this change was working and now it is not. I can't figure it out and if I change the "Do Not Convert Compliant MPEG Files" it will re-encode the whole thing and crash. But it does convert the audio to bitstream.
There is another solution but it would take 10 hours to explain it and uses two different programs to make it compliant.
Pinnacle 10.7 does have a nice solution but it takes about 10 hours on a duel core machine to make the file compliant and you still have to use Ulead to make your final HD-DVD.
I hope this helps.
