I am trying the Windows beta of the SheerVideo Codec. It shows up under the Render options fine but no matter what setting I choose it will instantly shoot to about 10% and than stop/crash with the error "A error occured while converting with a codec" (Well duh!). Vegas doesn't crash - just the codec. Was wondering if this is something being looked into Vegas 4 wise or if anyone has tested it with, um...er...Vegas 5?
