Nero, wmp & .flv

Hi, I am currently running NERO 7 Ultra Edition version 7.8.5.0 under WinXP Pro. I prefer to view all video through WMP 11. Currently I can play .FLV video with no problem. WMP shows that it is using the NERO Video Decoder to play. If I try to upgrade NERO to a newer version, I lose this ability. Audio plays fine, but no video.

Any suggestions?!?

Thanks in advance, Bob

Anyone?
