I've just looked the source of ggg
log.com and noticed that all mp4 files are hosted remotely at ggg
tube.com
As about the video player. The site uses popular freeware KVS Player:
http://wordpress.org/extend/plugins/kvs-flv-player/ - yes that's my plugin too
As far as I can see there is some issue with the original content host (gggtube.com), which can't stream video with position jumping. So there is no relation with the CyberSEO and KVS FLV Player plugins.
