So far I'm leaning towards JMB's TubeX because it seems to be the only one of the reasonably priced scripts which can generate animated thumbnails. Still need to look further into this but it's on my 'must have' features list since I think a tube site needs those to keep surfers coming back. Plus I agree with Wazza about JMB's stuff in general. I've used most of Jeremy's scripts over the years and support is always good (and upgrades free). I wish it was out of beta but I can deal with that I think.
I liked TEVS but no animated thumbs, and stats functions need more detail.
I like MechBunny but at $1,500 (to start) it's more than I need, and definitely more for someone who wants to have users uploading content.
I still need to spend some time with Tube Ace to see how it stacks up and if it can make the animated thumbs.
Anyone use Tube Ace?
Or actively using TubeX on a site?
Or have any other input?
