Hi Jason,
Thanks for posting! Before your post I had never heard of another good FLV player besides the JW FLV player. It's funny that I didn't find it because I had actually been looking for one. The JW FLV player is licensed such that I cannot include it in the Shadowbox distribution. However, the nonverblaster player looks like a great alternative. I'm going to look into this further and see if it would make a good permanent replacement for the JW FLV player.
I'd like some input from others on this issue as well. How tied is everyone to the JW FLV player?
