Mark Glaser, who runs PBS' MediaShift blog, wants your input on how video search from Google, Yahoo!, MSN, Blinkx, etc. is performing - what you can find, what you can't and how it all works.

Now maybe I’m searching for something that’s squarely in the hands of NBC, which has U.S. rights to those Olympics Games. Or maybe this is an event that happened too far in the past. This is where you all come in. I ask that you try doing your own search for video using these services, and others I haven’t mentioned, and report back to us on your results. You can either use the Feedback page, which goes directly to my email in-box, or you can report back in the Comments below.
