I was hoping to find some feedback on a difficulty I'm having with the AIW Radeon SPDIF out, ATI support has not been too helpful and I haven't seen anything like this problem in searching the forum. To give you a little background, after installing MMC 7.0 and enabling SPDIF in the DVD player I can get Dolby Digital sound to my receiver using the AV out cables on the back of the AIW, but I can't get any DVD sound from my SBLive! 5.1. This is not the problem, I can live with this setup.

However, when replaying captured MPEG-2 video from the ATI TV proggie the sound plays for a fraction of a second, then drops out. This does not just occur at the beginning of the clip either, if I advance to the middle the same thing happens, so it's not a case of a corrupted file. The strange thing is I have the same thing happen whether I'm using the ATI file player or the Microsoft media player. This does not occur with MPEG-1 or AVI.

So I figure that if I upgrade to MMC 7.1 it might get rid of the problem. Sure enough, it does! Now I can even hear uninterrupted sound in captured files that I made before the upgrade. However....

In order to install MMC 7.1 I uninstalled the previous version, including the DVD player. So after installing MMC 7.1 I installed the upgraded DVD player 4.1. Now I can't get the SPDIF out to work! Strangely, for the first time I'm getting DVD sound passthrough to my sound card. It is connected to my receiver using the 6-ch connection; I would prefer to use the SPDIF from the AIW, since that way I know I can get true Dolby Digital. No matter what I have tried (installing latest DVDGenie, following the Radeon guide at dtvmax.com, flicking the SPDIF checkbox on and off, restarting the DVD player) I can't get SPDIF back. This occurs even though I allowed the uninstaller to save my user settings.

After speaking to ATI they wanted me to try going back to my original installation from a backup and install MMC 7.1 and reinstall the DVD player from my CD (4.0). This also did not help. After going to my original setup again from a ghost image, I went so far as to try to install various parts of MMC 7.1 over MMC 7.0 to get rid of the MPEG-2 sound problems, but that didn't work either. My tentative conclusion is this: I can't fix the MPEG-2 problem without installing MMC 7.1 fresh, but once I do this my DVD player (4.0 or 4.1) SPDIF cable out is broken.

Has anyone encountered anything like this and been able to get past it? Currently I am back to MMC 7.0 (thank you Norton Ghost), but once again I'm having trouble with MPEG-2 sound.
