I am playing around with vista and am able to get WMP11 to open my EVO file, however it wont play, if i click the time bar anywhere the correct image shows, so it knows the file is there. the file properties show everything correctly, 1920x1080 and have both audio and video decoder. but it wont play? thoughts? Also i am testing out Microsofts Expression Media Encoder. Seems to work great, but same thing sort of. I can import the EVO file, i can even preview the encoding, but when i try to encode the file it locks up and says unknown error. I am getting close, anyone have thoughts on what i am missing? End result would be to encode my HD DVD EVO files to VC-1/wmv 720p.
