| That would be because TMPGEnc uses an ACM decoder for audio and there is no AC3 ACM codec. It probably would accept it if you cranked the directshow prioity and had AC3filter installed and set to downmix to 2channels.
Much better though to just use BeSweet or HeadAC3e to downmix/convert to mp2, then just multiplex with your video.
You could also have just set DVD2AVI to downmix and decode, however you wouldn't get as good a quality. |
