Mouse Roll Over & Play Video

Hello SI Team

I am really sorry that I bring this up again.

If you go here:
http://finalbug.net/blog/entry/400-edit-in-resolve-the-fcp-way-part-01
And roll over the thumbnail you can play the video.
If you go here:
http://finalbug.net/blog
And roll over the same thumbnail "Edit in Resolve the FCP Way Part 01" you can not play the video.

i.e. you can play the videos on the individual Blog pages but not on the Blog List Page.

I know that you have been very obliging in the past and hope that you can help out here again.
The mad thing is that I am pretty sure that this has been working for months on the Blog list page and suddenly it seems to be broken again. To the best of my knowledge I really did nothing to break this!

Please help me with this. It is the weakest link in chain that holds my web site together as of now. No doubt every thing will get better when ES 1.4 & EB 5 are here...

thanks in advance

Paul
