Can't Do AAC to AC3 with FFDSHOW: Errors Out and Closes

[dougdude9]

Ok, I have completely rebuilt my laptop... reinstalled Windows 7 64 bit. Downloaded all critical updates, installed Shark 32 bit and then the 64 bit components.

When I try the ac3 encoding now, it no longer crashes, but the video won't play. Just a black screen. I can uncheck ac3 endcoding and it will play, but it does just 2 channels... hence why I'm trying to get it to ac3 on the fly.

Here is something very interesting. In graphedit or graphstudio... whatever it is called, it says the audio being used in this aac mp4 files is the ACM Wrapper. I don't understand how this can be because I have everything set in shark to use ffdshow. I stopped fiddling with 64 bit and for now I'm just trying to get 32 bit working... although my goal is 64 bit for 7Media Center. So I have in the 32 bit shark settings the ffdshow selected for aac in directshow. Then the ffdshow audio settings I made sure aac and ac3 are being decoded. I check ac3 endcoding and according to graphedit, it still uses the acm wrapper which is in c:\windows\syswow64 or something like that... filename is quartz.dll.

I don't understand how or why it is using the acm wrapper. On the swap tab I have disabled all windows stuff... still no luck. I have downloaded that one tweakerfilter tool and disabled all the windows stuff... still uses the acm wrapper.

I have tried several changes and I can only get it to use the acm wrapper and sometimes I get it to use something called windows dvd-ht or something like that... either way, I know I don't want to use either.

It appears in freshly rebuilding my pc, I have gone from one problem to another. This is crazy! I'm wondering if I need to disable UAC instead of having it enabled like it is suggested.
Any ideas?

Thanks,
Doug
