Video overlay

Does anyone have any experience using Ambery's video overlay processor (http://www.ambery.com/pcvgatovimeg.html) for adding speaker names, hymn text, etc.? Or other good options for doing this without a Videonics mixer?

I have not had experience with the model you are asking about but I have used this one, which was $250.

I was sorely disappointed with the quality, features and fonts.

That's disappointing. Looks like the one you used is just an older version of the one I was looking at, made by the same company. No one's found a decent way to do this for a reasonable price? Any way to do it in software with an Osprey 260e card and WC software?
