Is the best suggestion to wait until this weekend?
I suppose that depends on what you are waiting for, and why. It sounds like there are improvements coming that should interest you, but then there are considerable improvements already available in 0.9.9.4. As long as you take the recommended precautions, there's no reason not to run a beta and 0.9.8.20 at the same time. Then you can make your own decision as to which to use on a regular basis. (You probably don't want to run two databases "in parallel.")
It may not be a good idea for you to rush in switching to 0.9.9.5. Allow a little time for more experienced users to discover if there are any significant problems. On the other hand, if you can't wait, you could try 0.9.9.4 right now.
From the comments Reset has made, I assume his script will work in both beta versions, and he plans to write a separate one for 0.9.8.20.
I'm still curious... Is PVD not extracting the same information from your video files that you have been getting with GSpot?
