Thanks again for your time and patience John.
Tried doing the above and still have the same results- (can’t play audio in architect- although it plays in vegas).
Also received an error message with reference to audio stream.
I’m wondering if there seems to be an issue with reference to windows media player and VLC as i tried to render seperately- please see results detailed below
Went through some other threads and rendered separately and what happend was that the video played in windows (without sound).
I then rendered the audio seperately and found that i could hear the audio (which played through VLC) but without any video.
Sorry for being a pain but this is becoming so frustrating.
Thanks
Mick
