You need java for the transition.. unless you're linking directly to the FLV or SWF file, which would load in the browser normally...
However you can't do something like that without JS:

1 of the links on each row is an Ad, so watch what you're clicking on.
As for the compatibility issue - it's a rule in all link lists that the video should be downloadable... which means that when I do my sites there's going to ba a download link next to each stream. Also... you know that not everybody plays WMV, but there're a lot of people using it.
I seriously doubt that the percent of people having the required version of Flash for FLV playback is so low. And the numbers that I mentionned before are from stats that I've read long before Adobe bought Macromedia
