Bit of mystery here, external preview was working in DVDA 2 and now it's stopped. Still works fine in Vegas 5. Now that I've got it I found it very useful for checking how text lines up with the raster lines but now it dain't work anymore.
About the only think I haven't tried is a reboot.
Same here, worked fine and then....tried a reboot and it sort of worked when I changed the aspect ratio to wide screen? Maybe a bug? Reinstalled and repaired the installation, seemed to work for a short while...maybe something in my setup, although I have set it up as per the instructions..Cheers
