So, just a note to one and all:

1] Check your Media > Properties > Final render are at least similar? If not then maybe give Vegas a hand and alter at least one of the variables - And YES I do know Vegas is Media Agnostic!

2] Make sure you have the latest update installed.

3] Disengage any FXs so you can see IF that was the issue.

Cheers

Grazie

PS: Did I suggest always getting the latest update? It's what updates are for . . getting the Fixes IN and the bugs OUT!!
